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.

Abstract

This study aims to investigate the impact of masonry infill walls on the behavior of reinforced concrete frames under seismic loads. Traditionally, masonry walls have been considered non-structural elements; however, their interaction with the overall structural behavior is crucial, especially in earthquake-prone areas. Understanding how these walls affect structural performance is essential to ensuring safety and effectiveness in design. This study employs a comprehensive literature review to analyze various factors influencing the performance of masonry walls in reinforced concrete structures. The key aspects examined include material properties, lateral load capacity, energy dissipation ability, and structural deformation. An evaluation is conducted on experimental test results from previous research. The findings reveal that the addition of masonry infill walls significantly increases the lateral stiffness and load-bearing capacity of reinforced concrete frames. Specifically, the study shows that structures with solid masonry walls exhibit a base shear force 1.2 times greater than those with clay brick walls. However, the study also highlights the reduction in deformation due to the brittle nature of masonry, which can lead to shear failure under ultimate load conditions.

Abstract

This research evaluates the impact of adding masonry walls on the stiffness and stability of building structures, focusing on pushover analysis and seismic behavior through a review of several journals. According to the research conducted by Hutajulu et al. (2019), masonry walls serve as significant structural elements rather than mere non-structural components. Through numerical analysis of the curves in the study, it was found that structures with masonry walls have a higher peak stiffness of 27.362 kN/mm, capable of withstanding a maximum load of 7490.93 kg with a displacement of 15.058 mm, compared to portals without walls, which only achieve a peak stiffness of 10.386 kN/mm and can withstand only 1451.91 kg. The stiffness difference between both portals reaches 66.242%. Similar studies by Majumder et al. (2017) and Mukhlis et al. (2022) also yielded comparable results, indicating that structures or portals accounting for the addition of walls exhibit significantly greater stiffness compared to those without walls, with stiffness differences exceeding 50%. In addition to its effect on stiffness, the addition of masonry walls also impacts the base shear capacity that the portal or structure can bear, as the inclusion of walls allows for greater lateral forces to be resisted compared to conditions without walls. For instance, in Hutajulu et al.'s (2019) study, the base shear for bare frames was only 14.025 kN, while infilled frames reached as high as 74.918 kN. These findings demonstrate that incorporating masonry walls into structures or portals enhances their resistance to lateral loads compared to those without masonry walls, contributing additional strength, stiffness, and earthquake resilience to the structure. Therefore, masonry walls should be treated as integral structural elements in building design to ensure safety and optimal performance under various load conditions.
