Numerical Analysis and Experimental Study of High-formwork Support System Considering Overall Spatial Action
In order to ensure the construction safety of the coiled high-formwork support system,the force state can be grasped by establishing a numerical model of the high-formwork support form,to simulate the force in accordance with the loading method on site before placing concrete.For the problem that the loading mode of the existing numerical model of the high-formwork support differs from the actual construction,and considering the overall spatial action of the high-formwork support when placing concrete,this paper takes an under-construction high-formwork support project in Qingdao as the research object,and uses ANSYS finite element software to establish the rigid plate model and elastic plate model of the high-formwork support for analysis.In order to verify the applicability of the two models,the results of the numerical analysis of the two models were compared with the experimental values,and the results showed that,the calculation results of the two models as a whole could reflect the trend of the force changes of the high-formwork support.However,for beam-slab structures with smaller spans(up to 10m),the results of the rigid plate model are more consistent with the test values,while for beam structures with larger spans(around 30m),the results of the elastic plate model are more consistent.When analyzing the force of high-formwork support,the calculation results are more reliable by combining the two models according to the different span structures.
