Design Analysis of Long Cantilever Steel Structures:Taking Zhengzhou International Cultural Exchange Center Hotel as an Example
In order to meet the functional requirements of the building,achieve the appearance effect of the building,and ensure the economic safety of the building structure,this project adopts a steel tie rod long cantilever scheme.Perform multi model and multi software comparative analysis using PKPM,YJK software,modal response spectrum method,elastic time history analysis method,and elastic-plastic time history analysis method;Adopting performance-based design,the shear wall in the bottom reinforcement zone is designed with mid seismic shear elasticity and bending non yielding resistance.Long cantilever steel beams,steel tie rods,and their supporting frame columns are designed with mid seismic elasticity.Finite element internal force analysis is conducted on the floor slabs in the long cantilever and adjacent areas,and reinforcement measures are taken.Finite element stress analysis is conducted on the steel tie rod nodes.
