Experimental Research And Structural Analysis On Lateral Force Resistance Of Light-gauge Steel Combination Wall

In recent years,a lot of researches have been made on the keel structure of light steel at home and abroad.However,the analysis of the resistance of the composite wall with different supporting and adopting different wall plate arrangement is still shallow.In this paper,6 steel bars with different supporting forms were built with 1: 2 monolithic wall,and the lateral force performance of the steel keel wall model was studied experimentally.In this paper,the main conclusions are as follows:(1)Three different skeletal systems were set up,which were normal skeleton,oblique support skeleton and angle support skeleton.The displacement of displacement(10mm)was obtained by the experimental device.In the pure skeleton,the results show that: with the changes of skeleton structure,give the same side shift,the general skeleton of the test force required for the smallest;with bracing of the skeleton test force followed by the ordinary skeleton 2 times;Of the skeleton of the test force required is the largest,is 3 ~ 4 times the normal skeleton is the skeleton of the brace 2 times.(2)After the three kinds of skeleton were attached with the steel wire mesh,the results showed that the bearing capacity of the model members was increased by about 32% after brazing the steel wire mesh.After the skeleton covered with steel wire mesh can be increased by about12.5%,covered with gussets skeleton covered with steel mesh can be increased by about 9.2%.That is,the steel mesh in the case of small skeletal stiffness can be improved more,when the skeleton stiffness is not obvious when the increase.(3)After the three kinds of skeleton were attached with the steel wire mesh skin,the test pieces were attached with the particleboard skin.The results showed that the anti-lateral ability of the model covered with particleboard was much better than that of steel-Corresponding to only steel wire mesh skin data were increased by about 250% 、 230% and210%,and the shear strength of plate components is relatively strong,but the particle board in the case of each frame is not a big difference,but the particle board is more suitable for ordinary skeleton Combination,and have a higher price.(4)The test equipment in the three skeleton attached to the steel mesh after the skin,and then coated with cement mortar,the results show that: mortar model bearing capacity of the mortar to improve more,corresponding to the steel mesh data were increased about 290%、310%and 270%.Compared with the panel of OSB,coated with cement mortar model is also significantly improved compared to OSB panel.(5)Combining this experiment with the generational pull method mentioned in the Japanese norm,this paper puts forward the theoretical calculation method suitable for this experiment.
