Behavior of Hinges in a Building with and Without Lateral Load Resisting System Provided at Ends—Pushover Analysis
摘要
The principle objective of this paper is to compare regular bare frame with fixed base and regular building with Lateral load resisting system (LLRS) analyzed by Nonlinear analysis. Considering fixed base and performing linear analysis is conventional method. But subjecting the same bare frame to nonlinear analysis and observing the response is very necessary to study the behavior of the building. Usually of the building behavior changes when subjected to any load which is generally nonlinear. A 3D model of ten storey building with fixed base is selected. The building dimension 25 × 25 m with base as fixed is analyzed by nonlinear pushover analysis. The 3D model is modeled using SAP 2000 V.19.2.1 software. The behavior of hinges in case of bare frame and bare frame with LLRS is studied and compared for nonlinear analysis. The LLRS adopted in this model is shear wall and the shear wall is modeled as shell element layered with nonlinear material behavior. The nonlinearity is incorporated by applying reinforcement to shear wall. The shear wall is provided at ends and the model is subjected to nonlinear analysis to study the behavior of hinges. The results obtained in case of both bare frame and bare frame with LLRS is tabulated. The results in case of displacement, base force, number of hinges and time period are compared and the behavior is studied. The results indicate that shear wall provided at ends shows better result.
