Abstract

Sumatera Island is a very active seismic area in Indonesia, which is crossed by the infamousPacific Ring of Fire. The western side of Sumatera Island suffers more from the groundshaking due to its closer distance to the epicenter. Combined with huge coverage of soft soil,building structures built on this island may experience excessive deformation and eventuallycollapse in a brittle way. For high-rise reinforced concrete (RC) building, the impact is evenmore devastating and may endanger its occupants. Due to these facts, this study aims toanalyze the deformation characteristic (story-drift) of high-rise RC building under earthquakeloading in Sumatera Island. Modal response spectrum analysis is performed to compute themaximum story-drift of three RC building models (10 story, 15 story, and 20 story) used in thisstudy. The seismic acceleration response spectrum function is derived from the lastestIndonesia’s Seismic Hazard Map (2010) and SNI 1726-2012. Eight capital cities in SumateraIsland and three soil conditions (soft, medium, and hard soil) are selected to generate 24seismic acceleration response spectrum functions. Combined with three RC building modelvariations, 72 story-drift data are obtained for each X and Y horizontal direction. Based on theanalysis result, taller buildings in soft soil condition are at greater risk to experience excessivedeformation due to seismic loading. Seismic locations in the western side of Sumatera Island isalso observed to exhibit higher seismic hazard compared to central and eastern side ofSumatera Island.Keywords: artificial neural network (ANN), earthquake, modal response spectrum analysis,structural response, Sumatera Island

Abstract

Bagasse is a waste material and the use of this material for construction is still limiterd. In this study, fiber extracted from bagasse was used in teh concrete. This research aimed to examine the mechanical properties of concrete, namely compressive strength, bending strength and split tensile strength. The percentage of bagasse fiber used was 0.3%, 0.5% and 0.7% of the weight of coarse aggregate. Compresive strength was tested on the age 7 days, 14 days, and 28 days, while the flexural strength and split tensile strength were tested on the age of 28 days. Workability test conducted on specimens contained 0.3%, 0.5%, and 0.7% of bagasse showed the volume of slump at 8 cm, 6.5 cm and 4.5 cm. In testing the compressive strength of concrete, the highest value was produced from normal concrete which was 22.92 MPa.The value of flexural strength of concrete increased by 9.47% from the normal flexural strength of concrete with the addition of 0.5% bagasse at 4.45 MPa. Different with the value of concrete split tensile strength, the highest value was obtained in the addition of 0.3% bagasse, which was 2.21 MPa with an increase of 19.48% of normal concrete. This research concluded that the addition of bagasse fiber can reduce workability.On compressive strength testing with the addition of bagasse fiber, the compressive strength was lower than that of normal concrete but still within the range of concrete plan quality 17 MPa. Addition of bagasse fiber to the concrete mixture could increase the flexural strength by 0.5% and split tensile strength by 0.3%.With the addition of bagasse fiber to concrete, it is hoped that bagasse waste can be utilized and concrete quality is achieved Keywords: Fiber Concrete, Bagasse Fiber, Split Tensile Strength, Flexural Strength, Compressive Strength

Abstract

Light brick is a brick that has a specific gravity ranging between 600 to 1600 kg/m3. Light brick has the main raw material consisting of sand, cement, water, coupled with a foaming agent material. The aim of the study was to obtain the composition of the optimum light brick mixture which resulted in maximum compressive strength. The compressive strength of the lightweight concrete was measured by applying compression displacement-controlled loading system. The mixture of each composition for the lightweight concrete used in this study was compliance with Ministry of Public Works module for lightweight mortar technology heap foam material for road construction. Light brick composition was varied based on the percentage of foaming agent and sand. The optimum composition has 25 kg cement, water as much as 13 kg, sikament NN 200 ml, sand as much as 64 kg and foaming agent as 5.7 kg of 12 samples of the test specimen. The compressive strength of optimum composition at the age of 3, 7, 14 and 28 days was 0.264 MPa, 0.364 MPa, 0.511 MPa, and 0.648 MPa, respectively. Based on test results, it was concluded that the addition of the foaming agent and sand would increase the compressive strength of the light brick.

Abstract

The increasing in the population has an impact on the increasing of housing or bulding demand. The alternative solution to reduce the use of cement is by leveraging on natural materials such as baggase ash as a substitution part of cement in the concrete mixtures. Results from test showed that silicte (SiO2) content in bagasse ash was dominant, so that it might be used as a cement substitution to enhance the properties of the concrete. The specimens were tested at 7, 14, 28 and 56 days of treatment to observe the development of bagasse ash concrete with the variation of the ash at 5 % and 10 % from the weight of the cement. The result showed that the higher percentage of bagasse ash would result lower workability. The compressive strength has also decreased from normal concrete at 28 days of the treatment, at 5 % variaton that has a compressive strength at 21,221 MPa and 10% variation has a result at 16.411 MPa. Propertional to compressive test, the flexural test has also decreased from normal concrete, at 5% variation has a flexural strength at 3.60 MPa and at 10 % variation has a result at 3.40 MPa. It was because imperfect of bond between Ca(OH)2 with SiO2. Hence, instead of cement substitute, bagasse ash rolled better as filler in concrete mixtures.

Abstract

Concrete is a construction material that is widely used in construction because it has many advantages. One of the advantages of concrete construction is that it is resistant to fire. However, the occurrence of a fairly high temperature change will have an impact on concrete, one of which is the change in the strength of the concrete. Therefore, this research was conducted to determine the physical change and the change of strength in post burn concrete. The concrete strength was measured with hammer test and compressive test. 18 concrete cylinder with size of 150 mm and height of 300 mm were fabricated with 3 quality variations, namely 20 MPa, 25 MPa and 30 MPa. Concrete were burned for 30 minutes with the temperatures range between 680-700 oC, and the concrete strength was calculated by using Nash’t and Agunwamba equation. The results showed that the concrete strength predicted by using Nash’t formula was 17, 18 and 21 MPa, respectively whice those predicted Bay pusing Agunwamba was 21, 23 and 26 MPa respectively.Keywords: Compressive strength, concrete after burn, Hammer Test, Compression Testing Machine (CTM).

Abstract

Sturdy bridge construction has always been synonymous with large and impractical structures. New innovations are needed to create a bridge system that is practical but also robust in terms of strength. For this reason, pedestrian arc bridges are analyzed with deck variations. The purpose of this study is to obtain the optimum bridge model, in which the ratio of weight of bridge structure deflection is small. Three types of bridges were considered in this study e.g deck arch, through arch and a half through arch by comparing the stresses that occur as well as the weight ratio and bridge deflection. The most optimum bridge is that produced the smallest efficiency ratio value. The results of the analysis obtained are A Half-Through Arch which has the best performance in distributing internal forces evenly. The Deck Arch weight is 1,125.52 tons, A Half-Through Arch weighs 1,007.14 tons and the Through Arch weighs 975.61 tons. The maximum deflection on the Deck Arch is 243.41 mm, A Half-Through Arch is 309.95 mm and the Through Arch is 260.19 mm. Then, the efficiency ratio of Deck Arch is 4.62, A Half-Through Arch is 3.25 and Through Arch is 3.75. So, it can be concluded the most optimum bridge is A Half-Through Arch with the smallest efficiency ratio value of 3.25. A Half-Through Arch are more efficient 13.34% than Through Arch and 29.73% more efficient than Deck Arch.Keywords : Analysis of Bridges, Arch Bridge, Steel Bridge, Bridge Loading, Deflection, SAP2000.
