Numerical analysis of reinforced ECC portal frames

Abstract

The present research study is based on numerical modeling for predicting the response of steel-reinforced engineered cementitious composite (ECC) portal frames under monotonic loading through finite element (FE) analysis on ABAQUS platform. For this purpose, a total of six portal frames chosen from the literature are modeled and analyzed. Among these six frames, two are fully made of concrete, two are fully made of ECC and remaining two are partially made of ECC and concrete following two reinforcement patterns prescribed in Indian Standard: 13920 (1993) and IS: 456 (2000). The results are obtained in terms of load-deflection response and the load-strain response at strategic locations, and damage patterns. Further, the load-deflection response and damage patterns of the frames from the FE analysis are compared with the experimental results available in the literature. It is observed that the results from the present numerical study show close agreement with the experimental results, which confirms the robustness of the modeling procedure employed.
