- Abstract:
-
Taking the Jiayuguan Guanghua building as the research object,we use the ANSYS software to build a pure wood structure and a brick-wood mixed structure Guanghua building models.based on the relationship between tenon-mortise joints,bucket arch nodes,and column-wall contact.Through model analysis and dynamic time-series analysis of various input seismic waves,the following conclusions are obtained:the brick tube structure greatly improves the low-order natural frequency of the Guanghua building,and the natural frequency gradually equals in the high-order mode.The displacement response of the pure wood structure model under the ground motion is greater,but it is still less than the limit of 1/50 of the displacement angle between the elastoplastic layers of the wood structure building.The brick wall structure significantly increases the peak acceleration of the structure under seismic time-series analysis,which is related to the reduction of the structure's natural vibration period.The brick wall structure significantly reduces the peak displacement of the structure,which greatly contributes to preventing the lateral collapse of the wooden frame.Under the 8-degree rare earthquake,the plastic strain at the bottom of the brick wall structure and at the opening is large,which may be manifested by cracks at the bottom of the brick wall and the connection with the wooden door.
