MANNUAL AND SOFTWARE BASED NON LINEAR ANALYSIS OF RCC PORTAL FRAME

Rakesh R, Vidyashree D

Abstract: In recent days there is a lot of light thrown on behavior of structure post elastic limits and to understand the maximum permissible limits the structural members could be subjected before the structure reaches the limit where in it shall not be capable to with stand any more load and any repair or rehabilitation of structure stall not induce any structural strength. This report deals with Nonlinear Pushover analysis of rcc frame. A single bay portal frame of 6m length beam and 4m long column is subjected to manual analysis by slope deflection and kani’s method and is verified with software output values and the structural members are designed in accordance with Indian standard code in limit state method and its plastic moment values are validated.

Keywords: Portal frame, pushover analysis, Nonlinear static analysis, Manual validation, hinges, kanis method, concrete design
