Abstract

The effect of earthquake forces on buildings will certainly be different if applied to regular and irregular buildings. The performance of structures produced in irregular buildings will be different from the performance of irregular building structures for the same load intensity. In the earthquake resistant structure planning regulations, SNI 1726-2012 concerning structural irregularities. Where in this regulation there are two types of structural irregularities namely horizontal structural irregularities and vertical structural irregularities which are then subdivided into several types of irregularity. The study was carried out to compare the results of building structure performance with horizontal irregularity compared to regular buildings as seen from displacement, drift ratio, base shear, performance level based on ATC-40, differences in reinforcement weight. This research resulted in the largest displacement for the x-direction, namely the type A irregular building where it experiences a deviation of 0,49 m difference and for the y-direction of 0,44 m in the type A irregular building Type A. The biggest drift ratio of the x-direction and direction y is a Type B irregular building that is equal to 0,64 m for the x-direction and 0.57 m for the y-direction. The largest base shear occurs in regular buildings with Type B irregular buildings at 16.34%. the level of performance based on ATC-40 for all building models is immidiate occupancy, the biggest reinforcement need is the irregular building model B with a percentage difference of 11,20%.

Abstract

In designing structures such as portals, planning generally does not take into account filler components such as bricks as structural components, only considered non-structural components / flat sharing loads. In fact, the infill wall is composed of bricks with mortars which have a certain strength and rigidity. As a result, when an earthquake occurs, the most damage is to buildings with brick infill walls In this study, two types of high-level building floors were made, namely 5 floors and 10 floors with 2 structural models of each level, namely the open and closed portal structure models that function as hotels using soft soil types in the Padang area, so the total structure model 2 structural models will be analyzed. The thickness of the wall is assumed to be an arrangement of half-brick walls with three barriers and four barriers. In the analysis of the brick wall structure is modeled as a diagonal compressed bracing equivalent to a brick wall (full brick) and then compared to a brick wall which is considered a flat sharing dead load (open portal). To analyze the behavior of this multi-story building structure, a Non-Linear (Pushover) static analysis will be carried out with the SAP 2000 assistance program. The results of the study showed the influence of strength and stiffness of the brick wall for the 5-way portal x was obtained by 71%, for the Y direction by 65%, while the 10-floor portal for x direction obtained the value of the brick wall stiffness by 58%, Y direction by 48%, and for portal 15 floors obtained strength and stiffness value of X direction by 52%, and for Y direction by 41%. The results of the study also showed that the structure of a closed portal with a brick wall has a better structural behavior compared to an open frame portal structure, this is indicated in the deviation value, a closed portal structure has a smaller value than an open portal structure. From the comparison of closed portal structures with brick walls, it can be concluded that the value of the rigidity of a structure is influenced by the span length and thickness of the brick wall. The bigger and thicker the dimensions of the brick wall, the greater the strength and stiffness values affect a reinforced concrete structure. This can be seen in the results of the ATC-40 pushover curve value, the value of the X direction brick wall with a span length of 5 m is greater than the value of the Y direction brick wall with a span length of 4 m.

Abstract

Indonesia is an area prone to earthquakes. Earthquakes caused by the movement of the earth's plates are the biggest cause of earthquakes that will cause damage to the building structure. Earthquakes occurring in Indonesia often cost lives. However, it is certain that the cause of the loss of life is not directly caused by the earthquake, but caused by the destruction of the building that caused the collapse in the building.The purpose of writing the research is to determine the performance criteria of the university building's seismic performance from the performance point value using the ATC-40 code, showing the melamine scheme (plastic joint distribution) occurring from the calculation of the software program, knowing the collapse pattern of the building so it can be known the joints Suffered damage and suffered destruction of pushover analysis.From the results of the study, the structure of the building is able to provide nonlinear behavior indicated by the initial phase and the majority of plastic joints occur in new beam elements and then column elements. The performance level of the structure enters the criterion of operational which means that minor structural and building damage can be reused immediately.

Abstract

Indonesia is one of the countries in the earthquake region. Therefore, it is necessary to build earthquake-resistant buildings to reduce the risk of material and life losses. Reinforced Concrete (RC) shear walls is one of effective structure element to resist earthquake forces. Applying RC shear wall can effectively reduce the displacement and story-drift of the structure. This research aims to study the effect of shear wall location in symmetric medium-rise building due to seismic loading. The symmetric medium rise-building is analyzed for earthquake force by considering two types of structural system. i.e. Frame system and Dual system. First model is open frame structural system and other three models are dual type structural system. The frame with shear walls at core and centrally placed at exterior frames showed significant reduction more than 80% lateral displacement at the top of structure.
