Structural design of steel truss suspension system of library of Guangsha Vocational and Technical University
The library of Guangsha Vocational and Technical University adopts reinforced concrete frame-shear wall structure system.In order to meet the functional requirements of the building,the cantilever steel truss is set on the roof,and the steel hanging column is set at the end of the cantilever steel truss.The hanging column is connected with the steel beam of each floor to form a suspension system.The internal force elastic response and static elastic-plastic analysis of the structure under small earthquake and wind load were compared and analyzed by using YJK and MIDAS Gen softwares.Considering the synergistic effect of the upper and lower chord floors of the steel truss,the construction sequence was specified for construction simulation analysis,and pin joint were checked by ANSYS finite element analysis software.The results show that the structure has high bearing capacity and good ductility under the action of large earthquakes,and the structure is safe and reasonable.The pin joint has good mechanical performance,and the stress level meets the requirements.The use of steel-concrete composite floor in cantilever position can shorten the construction period,improve the assembly rate of the building.
