In India, damage cause by some major earthquakes, such as India/Nepal 2015, Sikkim 2011, Kashmir 2005, Bhuj 2001, Latur 1993, and Uttarkashi 1991, have raised alarms to professionals. The probability of seismic risk is higher in more densely populated Indian cities, such as Bhuj, Kashmir, Sikkim, Uttarkashi, as they come under the highest seismicity zone in India. Therefore, our primary interest is to investigate the seismic performance evaluation of the buildings in these seismic prone areas. Significant research has been conducted on the seismic performance of existing buildings. However, investigations on the seismic performance of a building with different country codes for the same earthquake event has not been explored, which is crucial in providing a deeper knowledge of the seismic performance of buildings. This paper presents a comparative study of an Ordinary Moment Resistant Frame (OMRF) building designed using three major codes, Indian (IS: 456-2000, IS: 1893-2002), British (BS: 8110-1997) and European (EC-2, EC-8). Six typical building models considered with earthquake (WiEQ), and without earthquake (WoEQ), and their assessments were interpreted using non-linear static analysis for determining their seismic performance. Seismic performance is compared in terms of base shear coefficient (BSC) and drift ratio that shows WiEQ models, at the drift ratio of 1.5%, the BSC was as follows; 0.78, 0.88, and 0.96 for the models designed for British, Euro, and Indian codes, respectively. The results show that the building models, that have been designed for the Indian codal provisions for both cases, performed well as compared to the other country codes. Base shear and drift ratio are the vital parameters that vary considerably among the building models. This aspect of the Indian code makes it a safer design methodology with higher reserve strength and a reasonably good displacement capacity before reaching the Collapse Prevention (CP) performance level.

It is known that buried polyethylene (PE) pipes exhibit good seismic performance owing to their flexibility and ductility. The use of PE pipes as buried pipelines is gradually increasing, but currently, there are no seismic design or seismic performance evaluation procedures for domestic PE pipes in Korea. In this study, a seismic design and performance evaluation procedure for a domestic fusion-type PE pipe was developed based on the response displacement method, which is relatively easy to apply. The procedure was based on a method of examining whether the sum of the axial strain induced by both normal and seismic loading was within the allowable strain of the PE pipe. While calculating the axial strain of the ground, a coefficient was introduced to account for the heterogeneity of the ground. A seismic review method for ground deformation, i.e., ground liquefaction, was also introduced. The proposed procedure will provide a useful technical basis for evaluating the seismic design and performance of buried PE pipes in future studies.

This paper explores the comparative study of building performances at its performance points with two different response reduction factors. RCC Building with Bare Frame, RCC Building with Shear Wall and RCC Building with Stiffness Asymmetry, these three types of buildings are used for obtaining better objective of the study. Pushover Analysis is performed in SAP2000 to get performance of the building.

The objective of this paper is to research seismic performance of the weak-axis column-tree connections. For this purpose, two specimens CTY600 and CTY900 were fabricated and tested in this experiment. From the test results, the CTY specimen successfully achieved a 5% rad story drift ratio without brittle fracture and the total plastic rotation reached over 0.04rad.

In India when structure engineer’s analysis and design a structure like buildings, they are checking it for displacement because of safety and control of damages; so in this paper a set of frames with different height of reinforced moment resisting frames were analyzed by two popular methods of performance-based plastic design method and direct displacement-based design method. For calculation of base shear, the IS code has been used in both methods and ETABS software used for seismic performance evaluation by nonlinear static pushover analysis. The results of analysis with different methods compared by suitable parameters and graphs, such as: (a) story lateral force, (b) beam seismic moment, (c) displacement profile and (d) capacity curve. Results show acceptable performance in 2 methods in terms of capacity and deformation

Structural Irregularities

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%.
