Abstract
This study attempts to evaluate the residual seismic resistance capacity of a building with cracked brick walls or cracked R.C. walls. Using finite element analytical software ANSYS, a beam-column frame and a wall-element analytical model with various ratios of height versus width was established to analyze the relationship between the fissure width and the story displacement. Examples of a seven and a twenty stories model, respectively, were created using 「ETABS」 software to acquire the story displacement. The result of this study proposed a feasible indication for evaluating the seismic resistance capacity for buildings under earthquakes.
The results show that the width variation of the oblique fissure in a cracked wall is directly proportional to the story displacement and the analytical results of 「column axial force」 has no contribution to the evaluation. In addition, the study suggests that the analytical results of「maximum story displacement」, 「column shearing force」 and 「column moment」 be suitable for the evaluation and lead to similar residual seismic resistance capacities.
