Abstract

SMA asphalt mixture is an asphalt mixture with gap graded, so this type of pavement requires a high asphalt content. High asphalt content in the mixture has positive and negative impacts. The advantage is that it can make the mixture resistant easily oxidization and can make increase the durability of the road pavement layer. The disadvantage is prone to drain down (a condition where the binder (asphalt) will flow or separate from the mix) in the form of cellulose fibers or polymer fibers. This results in a mixture of SMA which is more resistant to deformation, deflection, and cracking and is stable to withstand the load of the vehicle's wheels. The additives commonly used are synthetic cellulose fibers, called Arbocell and Viatop66. This product is manufactured in Rosenberg-Germany. The use of this product causes problems, namely the high price and depends on the dollar price, and requires additional procurement costs in the form of import costs. Therefore, it is necessary to find an alternative to replace the cellulose fiber with natural fibers that have characteristics that are close to synthetic fibers. Based on the literature review, several natural cellulose fibers that have been successfully used as additives for SMA mixtures are rice bran fiber, palm fiber, coconut fiber, and pineapple leaf fiber, coconut fiber, kapok fiber, corn cobs. With cellulose content ranging from 14 – 64%, it shows good performance. Therefore, pineapple leaf fiber with a higher cellulose content of 69.5%-71.5% has the potential to be used as an additive because it has a cellulose content that is close to synthetic fiber.

Abstract

Bridges are infrastructure buildings that are affected by technological developments. Beam structures on bridges often experience a decrease in strength, one of which is shear strength. Sometimes the shear capacity of reinforced concrete beam structures cannot meet the requirements at this time. This can be caused by increased loads, inadequate shear provisions in the initial design and material damage due to natural factors. Reinforcement methods by means of externally bonded (EB) and near-surfaced mounted (NSM) are methods that have been carried out to overcome the decrease in shear strength in beam structures. Shear reinforcement using the EB and NSM methods in practice only relies on epoxy bonding and concrete covers, this makes it susceptible to structural failure. Reinforcement method deep embedment (DE) can be used as a suggestion as shear reinforcement in reinforced concrete beams to overcome the previous problems. Reinforcement using the DE method is shear reinforcement which is reinforced at the core of reinforced concrete beams. The aim of this research is to analyzq the behaviour of reinforced concrete beams resulting from finite element modelling using ABAQUS software. This research was carried out by embedding 20 bars vertically with a distance of 100 mm along the shear span. The results of finite element modelling with ABAQUS software show that the maximum load obtained is 28,12 kN and the maximum deflection that occurs is 14,10 mm. The final result of the beam failure model is flexural failure. This is indicated by the initial crack pattern that occurs vertically in the middle of the beam span. The crack continues to propagate towards the compression area of the beam until the beam collapses.

Abstract

Beams are a rigid part of the structure of a building. This beam is specifically designed to be able to withstand and transfer loads to column. Beams without shear reinforcement will experience changes in behavior both in terms of strength and failure patterns.The shear capacity of existing reinforced concrete structures is often unable to meet existing requirements.This decrease in strength can be caused by increased load, strong shear that is inadequate in initial design and material damage due to natural factors. Many methods that have been done are by means of external bonded (EB) method and near-surface mounted (NSM) method. However, shear resistance using the EB and NSM methods is prone to structural failures due to the magnification of this method only to contain an epoxy attachment and its blanket. To overcome this problem the resistance method using deep embedment (DE) method have been proposed to reinforcement the shear capacity of existing reinforced concentrate structures.The purpose of this study was to analyze the shear behavior of reinforced concrete beams without shear reinforcement strenghtned by the DE method through finite element modeling.In this research, the existing reinforced concentrate structures put up the reinforcement by implant three kinds of steel carcass with 200 mm each gaps spread out shear beam. The maximum load result obtained from finite element analysis on reinforced concrete beams reinforced by the DE method was 29.09 kN. While the maximum deflection results obtained in finite element analysis was 10.1 mm. The failure model that occurs in the beam which is strengthened from the results of finite element analysis is the shear collapse.

Abstract

Bridges are infrastructure buildings that are commonly used and very functional in everyday. One of the structural components of the bridge is a reinforced concrete beam as a load bearer that will be forwarded to the foundation. The shear capacity of reinforced concrete beam structures sometimes cannot meet the existing requirements. This can be caused by increased loads, inadequate shear strength in the initial design and material damage due to natural factors. There are several methods that have been carried out to overcome the decrease in shear strength in beam structures, namely reinforcement methods by externally bonded (EB) and near-surface mounted (NSM). In reality, shear reinforcement with EB and NSM methods in implementation only relies on epoxy adhesion and concrete blankets, which still causes structural failure. The deep embedment strengthening method (DE) can be proposed as a shear reinforcement for reinforced concrete beams to overcome the previous problems. Reinforcement with DE method is a shear reinforcement that is reinforced in the core of reinforced concrete beams. This research was conducted by embedding 8 reinforcements vertically with a distance of 200 mm along the shear span. In this study, finite element modeling was carried out using ABAQUS. The results of finite element modeling with the DE method showed that the maximum load was 30.646 kN and the maximum deflection was 13.00 mm. The collapse model that occurs from finite element modeling on test specimens with DE reinforcement experiencing flexural failure.

Abstract

Fiber Reinforced Polymer is a combination of two main materials Resin Polymer (plastic) as a binder matrix and Fiber (fiber) as reinforcement. This material has three fibers, namely Carbon, Glass, and Aramid. Glass fiber was used in this study, because it has a greater strain compared to other fibers. This study aims to design reinforced concrete structures using steel reinforcement and GFRP as well as to compare the reinforcement requirements of each reinforced concrete. Calculation of reinforcement for steel reinforced concrete refers to SNI 1726-2019, while for GFRP reinforced concrete it is based on ACI 440 1R-2015. This research begins by collecting data in the form of a design structure drawing of a 6-storey hypothetical building, with a total building height of 23 m. The hypothesis building has the number of spans in the X-axis direction is 5 with a distance between columns of 6 m, while the number of spans in the Y direction is 3 with a distance between columns of 5 m. The column dimensions for all floors are 60 cm x 60 cm, while the beam dimensions are 40 cm x 40 cm. The thickness of the floor and roof slabs is 12 cm and the concrete quality is 30 MPa. For the calculation of structural loading, dead load, live load and earthquake load are used and the design of reinforcement for conventional steel reinforced concrete structures and GFRP is carried out. Steel reinforced concrete structures with GFRP reinforced concrete have differences in the amount and diameter of reinforcement required. For beam elements bearing steel reinforcement, 24 pieces of flexural reinforcement are needed with a diameter of 19 mm, while for beam elements, GFRP reinforcement requires 12 pieces of flexural reinforcement with a diameter of 1 inch to 1,128 inches. For the field area, steel reinforcement beam elements need 12 pieces with a diameter of 19 mm, while for GFRP reinforcing beam elements require 8 pieces of flexural reinforcement with a diameter of 0.875 inch to 1.128 inch. In column elements, steel reinforcement and GFRP reinforcement require the same amount of main reinforcement, which is 32 pieces. However, in terms of diameter, steel reinforcement requires 25 mm diameter reinforcement, while GFRP is 1 inch in diameter.

Abstract

Liquefaction is a process of changing soil properties when the solid state becomes liquid caused by cyclic loads as a result of an earthquake so that the pore water pressure increases, approaching and even exceeding the magnitude of the total pressure. Liquefaction occurs due to earthquakes that occur in the area. Tectonic earthquake is one type of earthquake that can trigger liquefaction. The purpose of this study was to examine the potential for liquefaction in Kulon Progo Yogyakarta as the location of the New Yogyakarta International Airport, analyze the safety score (FS), and the value of the liquefaction potential index (LPI). The method used is the Idriss – Boulanger (2014) method using SPT data which is tested at three test points, namely BH-01, BH-03, and BH-06. For this study earthquake data were obtained from the USGS site and the 2017 Earthquake Hazard Map with variations in the earthquake magnitude used were 5.00; 6.30; and 8.10 and ground acceleration data using a probability of 7% in 75 years with a return period of 1000 years. Soil classification based on USCS shows that the soil at the study site is poorly graded sand which contains little fine grain. The results of the study indicate that the research location is prone to liquefaction. Liquefaction occurs at each test point at depth of 4.00 m and 6,00 m, especially at Mw 8.1 and amax 0,48 g with variation where soil resistance is low. Then, based on the classification of the liquefaction potential index numbers which are in the low to high range and the estimated decrease that occurs is up to 23,6 cm.

Abstract

Pushover analysis as known as non-linear static analysis is one of the structural analysis procedures that is widely used in seismic assessment and performance evaluation of existing structures . In the nonlinear analysis procedure, the behavior of the structure due to external loads acting can be seen from the status of the joints formed. One of the joint models that is less commonly used in non-linear static analysis is the fiber hinge joint modeling. Fiber hinge is a nonlinear joint model that can consider distributed plasticity along with its structural elements. Study this learn possibility difference in results analysis use fiber hinge because properties component specified nonlinear _ researcher . In order to study the impact of the use of joint modeling variations in nonlinear analysis, a regular reinforced concrete structure model with 4 height variations namely 3, 4, 5, and 6 floors which were analyzed with two different types of joint modeling. Fiber hinges and conventional lumped hinges will be defined in the cross section. Research results show that the use of fiber hinge in each model produces score relative moment _ small however given rotation _ relatively more big than lumped hinge as well relative base shear value small than lumped hinges. Considering the fiber hinge is method that gives state of natural response so that deformation globally generated _ more big than lumped hinges. This thing take effect to determination structure performance value.

Abstract

Planning for existing construction requires taking into consideration the exact location of the structure; sandy soil is typically found in Indonesia, and pile foundations are a very frequently used type of support. Whenever the stable soil is located at a quite deep depth or when the building's foundation is situated on a relatively high embankment, the pile foundation is utilized to support the structure. Given the quantity of pile foundations utilized in Riau, where soft soil makes up the majority of the soil type, a study on pile foundations is necessary. A possible research approach involves conducting a small-scale pile foundation modeling experiment to determine the group pile's bearing capacity on sand soil, taking into account variations in the pile's length and space. Direct testing on a pile foundation model with length, spacing, and length variations of 20, 30, and 40 cm as well as spacing variations of 2.5D, D, and 5D was used for the research. Pile group length 40 cm has the highest capacity, according to the results of a direct loading test conducted with a spacing of 2.5D. According to the findings of the Terzaghi and Peck method interpretation, the pile with a length of 40cm and 2.5D spaces has the largest qult of 1.665 kN. A pile with a length of 40cm and 2.5D pile spacing is the pile with the largest qult of 2.232 kN, followed by a pile with a length of 30cm and a space of 2.5D. Based on the results of the investigation, it can be stated that Qult will get higher the more closely spaced the pile exists and that Qult will become higher the longer the pile is on the foundation model.
