Structural Performance of A 3D Reinforced Concrete Building Obtained By both Nonlinear Static and Dynamic Analysis
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 4
Abstract
The paper presents thoroughly the process for the analytical estimation of reinforced concrete structures structural vulnerability. In order to achieve this purpose, both nonlinear static and dynamic analysis have been implemented on a 3D standard reinforced concrete moment resisting building and the seismic response is obtained analytically by both methods. The selected building for illustration was designed according to older seismic codes and regulations (Hellenic Code of 1959) and without conforming to modern seismic detailing requirements. The 3D model was subjected to conventional Static Pushover Analysis and bidirectional Incremental Dynamic Analysis (IDA) with the use of SAP 2000 software program. IDA involves nonlinear dynamic analyses of the structural model under a suite of ground motion records, each scaled to several intensity levels designed to represent the structure’s behaviour ranging from elasticity to final global instability. The structural performance of the RC building under static and dynamic seismic loads was demonstrated in pushover, capacity, fragility and IDA curves which were obtained from the previous analyses. In addition, results of the two methods are compared and the assessed performances are discussed.
