Research and engineering application on anti-explosive performance of prefabricated prestressed channel slab
The anti-explosion performance test of prefabricated prestressed channel slab was carried out,and ABAQUS software was used to analyze the channel slab test,which verifies the accuracy of the finite element analysis.At the same time,the finite element software was used to simulate the channel slab with full size,and the failure form and force form of the structure under static and dynamic load were compared and analyzed.Finally,the engineering application of prefabricated prestressed channel slab in project was introduced.The results show that,the prefabricated prestressed channel slab is completely elastic under grade 5 civil air defense load,and only appears small tensile crack and small plastic deformation under grade 4 civil air defense load,indicating that the concrete channel slab can withstand grade 4 civil air defense load without damage.ABAQUS software has high accuracy in test simulation and provides a feasible solution for structural anti-explosive performance analysis.Prefabricated prestressed channel slab has good ductility under blast load.Prefabricated prestressed channel slab structure conforms to the requirements of prefabricated buildings in China,and has the advantages of saving time,saving labor,saving energy and high quality,which is conducive to the application and popularization in engineering.
