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.

Moment Resisting

This paper gives a brief presentation about different types of analysis, plastic hinge, moment-resisting frames (MRFs) and shear walls (SWs) in reinforced concrete (RC) Structures. ETABS computer software is employed to model and analyse the structures applying the pushover. The performances of the modelled structures are also evaluated considering different parameters such as the number of stories, spans length, shear walls, reinforcement yield strength and characteristic strength of concrete. The study includes two cases, which are moment-resisting frames with and without shear walls (i.e. MRFs and MRF-SWs, respectively). Each case covers low-, mid- and high-rise buildings. In this regard, a comparative study has been performed for the results obtained from all models. It was observed that the stiffness of MRFs compared to MRF-SWs was less and also the stiffness of low-rise frames was higher than that of mid-rise and high-rise frames. Technically this means that a low-rise building is stiffer than a mid-rise building and a mid-rise building is stiffer than a high-rise building. Additionally, when the span length increases, the stiffness of the building decreases. Therefore, it can be concluded that the span length is inversely proportional to the stiffness. Finally, all stiffness values were calculated taking into consideration the displacement and base shear at the first hinge formation on the pushover curve of each model.

Nonlinear Pushover Analysis

This paper compares multistoried frame structures on plain ground and on hilly areas, first under the action of normal commercial loading and thereafter by considering the effect under the action of heavy loads. Behavior of multistoried frame buildings on plains are completely different from buildings which are constructed on hilly slopes. Buildings constructed on plain is simple and symmetrical, whereas the buildings that are constructed on hilly slopes are complex in geometry and asymmetrical in nature. Similarly, the behavior of commercial buildings with normal loading is distinctively different in comparison to special buildings such as Data centre buildings which are heavily loaded under gravity. Four different types of Symmetrical and Asymmetrical analytical Models are generated for five and ten storey buildings using "ETABS". Seismic evaluation of these models is done separately under the effect of normal and heavy loading by performing Nonlinear Pushover analysis
