The defects of reflecting stiffness contribution of infill wall by period reduction

摘要

The infill wall impact on subject structure mostly is the effect of infill wall stiffness. The conventional design method is using the period shortening to consider the effect of infill wall stiffness. For it is too vague, this method didn't consider the differences of the number of infill wall impact to frame structure, and the differences of location on the same floor also not been considered. Because the difference is hard to consider, this article try hard to come up the frame structure conceptual design that considering the differences based on the practical project.
