Modeling and Validation of Experimental Test Results on Infilled Frame With Eccentric Reinforced Opening

Abstract

This research was conducted to find out how to model and validate experimental test results of the single-story infilled frame structure with eccentric and reinforced wall opening. Modeling method derived from this study further could be applied on complex model of full-scale building structures. Validation were being done on type 3/II and 4/II specimens from Sigmund and Penava (2012) experiment results. Specimen with full infill wall was also included as reference model. Stress-strain parametric relation curve of concrete by Mander et al. (1984) and infill wall masonry by Kaushik et al. (2007) were constructed and approached correspondingly by multiple straight lines to obtain elasticity modulus changes and lateral load stages. Number of stages of lateral load and modulus of elasticity changes then were applied to analytical models of each specimen to generate force-displacement curve. Curve of validation results from analytical model are visually alike to the experiment. There are five load stages applied to specimen 3/II and 2/III, while six load stages on specimen 4/II. Average deviation of displacement values for model 3/II, 4/II, and 2/III are about 36%, 5%, and 11%, respectively.
