Investigation On Seismic Behavior Of Sandwich Wall Panel With Angled-steel Column

Construction is graduating one of pillar industry with fast developing of national economy. Based on the policy about energy saving and continual development, It has theoretic and applicability value that bring forward new style walls suited for times and research on it.One of effective ways about building energy saving is that take heat-preservation measures to outer walls. According to the relative position between heat-preservation material and bearing wall, it was usually divided into three styles. That is, heat-preservation material was placed on the outer surface, inner surface and in the middle of walls. Each of style was adopted to some extent. However, the function of different materials cooperation wasn't considered generally.Sandwich seismic wall which concrete column was replaced with angle-steel truss was discussed in this paper in order to be used as outer-walls of multi-story shear walls system. It had double capacity of bearing and heat-preservation. Double side of concrete panel can bear and deform coincidently because angle-steel frame and steel wire confined, it ensured durable character of sandwich wall, too, due to thick of wall increasing, wall's stable bearing strength was improved.Though the pseudo-static test of three prototype-modal sandwich wall with angled-steel column, seismic behavior are discussed. Based on the concrete nonlinear analyzing theory, this paper constructed the finite element modal by ANSYS program and proved the modal by test result. Designed & further improved methods are presented on the conclusion of tests and calculations.
