Research On Reliability Of Frame Filled Wall Structure System Under Seismic Action

The frame-filled wall structure is one of the most widely used structures.Since the filling wall is often regarded as a non-structural member.the structural design does not take into account the role of the filling wall.only in the seismic design using the cycle reduction factor to consider the impact of the filling wall.However,in the actual earthquake.due to the role of the filling wall,many houses have been damaged,which makes us aware of the framework of the wall structure under the action of seismic reliability is necessary.In this paper.the following work is done on the reliability of the frame-filled wall structure system under earthquake action,and the relevant conclusions are drawn:(1)Based on the Pushover analysis method,a method to identify the main failure modes and the system reliability calculation is proposed.By comparing the methods of other researchers,the accuracy of the method is verified.(2)A simplified model of equivalent pendulum is proposed,which is based on the experimental data,which proves the rationality of the model.(3)To study the reliability of the structural system from the aspects of the number of floors,the layout of the filling wall,the location of the filling wall,the opening rate of the filling wall,the opening position of the filling wall.According to the data analysis,it is concluded that the reliability of the framework will increase with the number of floors;The reliability of the structural system of the filling wall is smaller than that of the pure frame structure.The more symmetrical the layout of the filling wall is,the more the seismic reliability of the structural system is.The maximum reliability of the filling wall structure system with the opening ratio of about 25%is the largest,and the 50%of the filled wall structure system has the least reliability.When the opening ratio is more than 75%.the reliability is not much changed;The opening position of the filling wall structure system is still affected,so in the actual project if the hole size is the same.the hole position should be arranged in the middle position or away from the side of the force side.
