Analysis and experimental study of vertical ultimate load bearing capacity of light steel dense-ribbed walls
In order to study the influence of different factors on the vertical ultimate bearing capacity of light steel ribbed wall,the finite element software ABAQUS was used to simulate the light steel ribbed wall with different column section size,col-umn spacing and wall height.Combined with the analysis results,four multi-ribbed walls were designed and static load tests were carried out.The results show that the numerical simulation of the light steel multi-ribbed wall is consistent with the failure of the test,and the simulated value of the vertical ultimate bearing capacity is in good agreement with the experimental value.According to the calculation method of vertical ultimate bearing capacity of light steel multi-ribbed wall given in the current GB 50017-2017"Steel Structure Design Standard",the calculated formula value is compared with the finite element simulation value and the test value.The maximum deviation is 0.109,and the ratio of the three is in the range of 0.95～1.11.The calculation results of the ultimate bearing capacity formula are in good agreement.
