| For decades, the steel output of China is growth rapid. The latest statistics data of China’ssteel industry association show that China’s steel output in2011reached683.265million tons.This will make the steel structure housing of our country develop rapid. The steel structurehousing is the product of social and economic development and the progress of science andtechnology in the construction. Steel frame is the main component for resisting vertical forceand its horizontal bearing capacity is weak. So we put the steel shear wall into the steel frame.The plate shear wall has good comprehensive benefits. It is a good component for resistinglateral force and has good elastic-plastic deformation ability that can absorb a lot of energy inthe earthquake. In order to making doors and windows open facilitate in the steel structurehousing system we open hole on the plate shear wall structure to better meet the requirementof the using function.This paper make static and dynamic analysis of two single layer steel frames-steelplate shear wall with opening, the main work is as follows:1.Using ANSYS to making steel plate shear wall structure unit finite element model. Thesteel frame choose beam element and steel plate choose shell element. Beam and columnconnected rigid.The whole structure fixed at the bottom and freed at the top. And verify thecorrectness of finite element calculation model with two test specimen reference in theliterature.2. Make stability analysis of two layer of single hinged steel frame, opening plate shearwall, steel frame-open plate shear wall unit. Parameters including high than wide, high thanthickness, location of the hole, the size of opening hole. Select the most optimal value of thestructure under different parameters. Provide the basis for the engineering design.3.Analysing the hysteretic performance of two layer of single hinged steel frame-openplate shear wall structure.This paper analyzes the ability to absorb energy of steel frame-openplate shear wall. Paint the hysteresis curve in different high thickness, different open position,opening size. Analysing the hysteretic performance of the steel frame-open plate shear wall ondifferent vertical loads. Got a certain rule and using it in engineering design.4.Making earthquake response analysis of two layer of single hinged steel frame-openplate shear wall. This paper choose EL centro wave, Taft wave and artificial wave to makeseismic analysis. Draw displacement curves of representative points on steel frame with holein the steel plate shear wall.Found the maximum displacement of this structure underearthquake effect. Found the time of maximum displacement appearing moment and themaximum point of process curve. Get basal shear curve under different seismic waves and compared with the input waves and found a certain rule. This rule can provide reference forengineering design. |
