Finite Element Analysis on Bearing Capacities of High-formwork Support System on Latin Hypercube Sampling
Study the changes in the load-bearing performance of high-formwork support systems under different defective components,provide guidance for the layout of high-formwork support systems,the combination and use of components,and prevent and reduce collapse accidents in practical engineering.Based on Latin hypercube sampling,considering the influence of component defects on the bearing performance of three template support systems with different installation parameters,0.1%~0.2%of the first-order buckling bearing capacity in linear buckling analysis is randomly selected as the hypothetical horizontal force.Finite element analysis is conducted on the performance defects of components to explore the bearing capacity and instability mode of the support system under different installation parameters.The influence of SPR on bearing capacity is greater than that of D and t,and the influence of dual factor coupling on bearing capacity is greater than that of single factor.The influence of the change in the distance between upright poles on the bearing capacity of the support system is greater than that of the distance between upright poles.As the number of coupling factors increases,the influence of step distance on the bearing performance of the support system will also increase.During the construction of the support system,the defective components will be dispersed and arranged to prevent the overall instability and collapse of the high-formwork support system.
