Performance based analysis is conducted on a structure to know the performance of building under severe earthquake loads with limited and well-distributed damage. To do this analysis a non-linear static analysis called pushover analysis had conducted on the structure. In this paper, an RC building with both 5 storey and 10 storey is designed for both gravity loads and earthquake resistant loads using SAP2000 software. Analysis is done in both X and Y direction to get a damage curve (pushover curve). By studying the damage curve, the results that obtained are earthquake resistant designed building had more strength when compared to gravity load designed building and it is better to consider earthquake in building design , because gravity loads alone cannot give the adequate results.

Current research works and observations indicated that parts of the Kingdom of Saudi Arabia have low to moderate seismic regions. Major parts of buildings were designed only for gravity load and were poorly detailed to accommodate lateral loads. This study aims to investigate building performance on resisting expected seismic loadings. Two 3D frames were investigated using pushover analysis according to ATC-40. One was designed according to a design practice that considers only the gravity load and the other frame was designed according to the Saudi Building Code (SBC-301). Results showed that the building designed considering only the gravity load was found inadequate. On the other hand, the building designed according to SBC-301 satisfies the Immediate Occupancy (IO) acceptance criteria according to ATC-40.

Indonesian territory which consists of several islands, both large and large and small, is an area that has a level of vulnerability. In this case heard and witnessed through the media various events from natural phenomena, namely earthquakes in recent years that hit several regions in Indonesia. The potential for natural phenomena to occur is very large because the position of the Indonesian archipelago is at the confluence of the Australian plate, the Pacific plate, and the Eurasian plate. This condition causes the need to comply with the principles of planning and implementing an earthquake resistant system in every building structure to be built in the territory of Indonesia, especially for areas that have a moderate to high level of earthquake risk or vulnerability. Research on the main structure of the LPMP office building with 8 floors aims to determine the behavior of the structure in response to static earthquake loads and dynamic earthquake loads. The method suitable for building design involving earthquake loads in the calculation is the equivalent static. This method  is only intended for regular horizontal and vertical SNI 1726(2012)buildings. One of the characteristics of a regular bulding is that the building’s height is less than 40 meters and 10 levels as seen from the building pedestal so that the building tends to be rigid and the building is low. Along with the development of the times, many software that can be used to facilitate an earthquake resistant building design in Indonesia have been revised to SNI-1726(2012). In earthquake SNI 03-1726-2012 article 7.1.3 it is stated that : the final value of the dynamic response of the building structure to the nominal earthquake loading due to the effect of a planned earthquake in a certain direction, should not be taken less than 85 % of the value of the first variety response. If the dynamic response of the building structure is expressed in nominal basic shear force V, where the value of the oh the nominal base shear for each static earthquake in the x direction is 0.867622 and the y direction is 0.975368 where the bigger the dynamic earthquake in the x direction is 3425.624 and the y direction amounting to 3550.92 so that the structural seismicity review shows the result that meet the seismic requirements stipulated in the SNI, starting from the building period, the mass participation ratio, the basic shear force of structural deviations.

We evaluated the performance of a high-rise residential building model in Purwokerto, Indonesia due to the seismic load. The evaluation was performed based on seismic loads given in the 2002 and 2012 Indonesian National Standard (SNI) using linear static analysis, dynamic response analysis and pushover analysis. Based on the linear static analysis, the drift ratio decreased by an average of 34.42 and 32.61% for the X and Y directions respectively. Meanwhile, based on the dynamic response analysis, the drift ratio also decreased by an average of 30.74 and 27.33% for the X and Y directions respectively. In addition, the pushover analysis indicates that the performance of this high-rise residential building model is still at Immediate Occupancy (IO) level. The post-earthquake damage state in which the building remains safe to occupy, essentially retaining the pre-earthquake design strength and stiffness of the structure. The risk of life-threatening injury as a result of structural damage is very low. Although some minor structural repairs may be appropriate, these would generally not be required prior to re-occupancy.

A method for a simplified modeling of post-and-beam timber buildings braced with nailed shear walls, useful for seismic design purposes, is presented and discussed in the paper. This strategy is based on the schematization of the vertical diaphragms through equivalent diagonal springs with elastic-plastic behavior and allows the assessment of the resisting ground acceleration by performing nonlinear static analysis; the Capacity Spectrum method based on equivalent viscous damping was applied. This nonlinear procedure constitutes a reliable and simple alternative to the linear static analysis using the behavior factor q. The procedures to determine the characteristics of the equivalent elements (stiffness and load-carrying capacity) are based on analytical evaluations, starting from the actual characteristic of shear walls. A comparison between the results of numerical simulation based of more refined and complex models, previously presented by the authors, and this time-reducing, simplified analysis proved the good reliability of the method.

AbstractInpres market block IV Pasar Raya Padang is not designed as a shelter building, but is designated as a vertical evacuation site when a tsunami occurs. This study aims to evaluate the structural performance of Inpress market block IV zone B. The method used for this research is the pushover analysis method. According to FEMA P-646/2019, vertical evacuation refuge structures are included in tsunami risk category IV, based on the risk category the maximum performance level is at the Immediate Occupancy (IO). For loads on buildings, refer to SNI 1727:2020 and SNI 1726:2019 for earthquake loads. For the calculation of the capacity of concrete structural elements, refer to SNI 2847:2019. Structural analysis was carried out using the SAP2000 version 16. After analysis, based on performance points, drift ratio that occur due to earthquake loading in X-direction and Y-direction are 0,05875% and 0,0067%. The maximum total drift that occurs is smaller than that required by ATC-40 for the Immediate Occupancy performance level, which is 1%. Thus, the structure performance level is Immediate Occupancy. This means that the Inpress market block IV building is still strong enough against earthquake loads.

Pembangunan konstruksi teknik sipil mengalami perkembangan yang sangat pesat seiring dengan berkembangnya zaman sehingga menuntut kita lebih kreatif dalam perancangan struktur baik dalam bentuk bangunan beraturan maupun tidak beraturan yaitu, bangunan setback dan bangunan soft story. Di Indonesia, tantangan yang dihadapi dalam kontruksi gedung bertingkat adalah adanya resiko akibat gempa. Salah satu metode untuk menganalisis beban gempa adalah analisis pushover. Analisis pushover merupakan prosedur analisis untuk mengetahui perilaku keruntuhan suatu bangunan terhadap gempa. Penelitian dilakukan untuk mengetahui seberapa besar pengaruh setback dan soft story yaitu bangunan tanpa dinding pengisi pada lantai dasar terhadap kinerja struktur akibat beban gempa berdasarkan hasil kurva pushover. Stuktur bangunan dimodelkan sebagai portal 2 dimensi yang tanpa adanya dinding pengisi pada lantai dasar yaitu terdiri dari 4 model rangka penuh, setback1, setback2, dan setback3. Hasil analisis dalam penelitian ini menunjukkan bahwa kontribusi dinding pengisi yang terbuat dari dinding bata mempengaruhi kekakuan lateral struktur, serta dengan dikuranginya setback pada struktur bangunan mengakibatkan nilai kekakuan semakin kecil sehingga nilai daktilitas semakin besar. Pada struktur gedung rangka penuh dan setback1 lunak kondisi bangunan sudah mengalami rusak parah atau runtuh saat terjadi gempa kuatdikarenakan terbentuknya sendi plastis pada kolom lantai pertama.  Kata Kunci : Analisis Pushover, Dinding Pengisi, Setback, Soft Story  ABSTRACT The construction of civil engineering construction has developed very rapidly along with the development of the era so it demands that we are more creative in the design of structures both in the form of irregular and irregular buildings ie, setback building and soft story building. In Indonesia, the challenge faced in the construction of multi-storey building is the risk caused by the earthquake. One method to analyze earthquake loads is pushover analysis. Pushover analysis is an analytical procedure to determine the collapse behavior of a building against earthquake. The research was conducted to find out how big the effect of setback and soft story that is building without wall filler on the ground floor to the structure performance due to earthquake load based on the result of pushover curve. The structure of the building is modeled as a 2-dimensional portal without the filler wall on the ground floor consisting of 4 full frame models, setback1, setback2, and setback 3. The results of the analysis in this study indicate that the contribution of wall filler made of brick walls affect the lateral stiffness of the structure, as well as with the reduced setback on the structure of the building resulting in smaller stiffness value so that the greater the ductility value. In full skeletal structure and soft setback1 the condition of the building has been severely damaged or collapsed during a strong earthquake due to the formation of plastic joints in the first floor column. Keywords: Pushover Analysis, Setback, Soft Story, Wall Filler
