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.

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.

Indonesia has a code for designing a seismic-resistant building, which has always improved year after year. Start from Peraturan Perencanaan Tahan Gempa Indonesia Untuk Gedung (PPTI-UG) 1983, SNI 1726:2002, SNI 1726:2012, and the latest one is SNI 1726:2019. SNI 1726:2019 experienced some renewal on designing a seismic-resistant building. This research aims to compare spectrum response design and the structural behavior between seismic-resistant building design using SNI 1726:2012 and SNI 1726:2019. The reviewed structure behaviors are base shear force (V), drift (δmax), and story drift (Δ). The study compares the detail of the structural components as well as using SNI 2847:2013 and SNI 2847:2019. The research uses a 10-story building modeling that serves as an apartment building and located in the city of Banda Aceh. Seismic analysis using a spectrum response analysis with Special Moment Resisting Frame (SMRF) structure. The result showed that the peak acceleration (Sa) for the class sites of Medium Land (SD) and Hard Land (SC) were 11% and 26%, respectively, while for Soft Land (SE), there was no increase. The shear force in SNI 1726: 2019 has increased by 19.75% for the X direction and 19.97% for the Y direction. The increase in the shear force is directly proportional to the increase in drift and story drift. In the beam detailing and beam-column connection, there were no significant changes. While in the column detailing, there are additional provisions that cause the transverse reinforcement to be tighter.

And Behavior

Malaysia is a country with very low seismic. Most of the buildings in our country may not consider seismic load during structure design, thus the level of safety for remains unknown. Recently, earthquake events have become more frequent. Therefore, engineers have to be alert and kept updated with the knowledge and behavior of earthquake trend in this area. It is vital to assess the precaution measures that can be taken and consider them in the future building design. Therefore, a decision making framework in designing earthquake resistant building especially for school building in Malaysia is needed to help engineers to consider earthquake risk in the building design. This framework employed NERA Program with the assistance of SAP2000 software for analysis of the performance of earthquake resistant building.

Cibubur is an area in the earthquake zone. The intensity of the earthquake increases every year; therefore, this must be watched out because it will cause the existing buildings to be short-lived. To deal with these problems, various ways are carried out such as making building stiffeners in the form of a shear wall. This study aims to determine the position of an efficient shear wall. The method for analyzing this shear wall was first modeled. The shear wall laying model was divided into four. With the four models, it would be able to choose which model was efficient to reduce the earthquake that occured. Analysis used ETABS software on each model, and output in the form of drift and base shear. These results will become a reference for effective model selection. Based on the results of drift and base shear in the direction of X and Y direction, of the four shear wall placement models of Tower B Trans Park and Trans Studio Cibubur, the most efficient in resisting earthquake loads is the original model. With a save value of direction X is 926.62 mm, and Y is 931.22 mm. The value of the base shear on direction X is 4691.71 tons, and Y is 4736.57 tons.Keywords: Base shear, Drift, Earthquake; Shear wall

Key Aspects

The present work aims at understanding and modelling some key aspects of the sloshing phenomenon, related to the motion of water inside a container and its effects on the substructure. In particular, the attention is focused on the effects of bottom shapes (flat, sloped and circular) and water depth ratio on the natural sloshing frequencies and damping properties of the inner fluid. To this aim, a series of experimental tests has been carried out on tanks characterised by different bottom shapes installed over a sliding table equipped with a shear load cell for the measurement of the dynamic base shear force. The results are useful for optimising the geometric characteristics of the tank and the fluid mass in order to obtain enhanced energy dissipation performances by exploiting fluid–structure interaction effects.

Storey Building

Building structures of low or medium height are usually designed with a pseudostatic approach using a base shear much lower than that predicted from an elastic spectrum. Given this shear force, the objective of this paper is to evaluate the effect of the element strength assignment (as determined by several building codes) on the torsional response of inelastic single-storey eccentric structures and to provide guidelines for minimizing this structural behaviour. It is demonstrated that the expected torque about the centre of mass (CM) may be, with equal probability, positive (counterclockwise) or negative (clockwise). This result means that the torsional strength should also be provided in equal terms in both rotational directions, and therefore the base shear and torque (BST) surface of a given system must be symmetrical (or approximately symmetrical). In stiffness-eccentric systems, appropriate BST surfaces may be obtained when a structural design is based on a pair of design eccentricities in a symmetrical order about CM, and this is shown in representative single-storey building models under characteristic ground motions.
