Abstract


Since the flourishing development of high-rise buildings , modern high-rise building structure due to the functional requirements of large space , often requires conversion layer structure . In the conversion engineering research , the conversion truss force explicitly clear structure weight and the lateral stiffness than the transfer beam small load transfer characteristics conducive to the layout of the ventilation and lighting and large pipes and other equipment can be make full use of the conversion layer of building space , excellent effect and buildings of architectural art function can be obtained on the building , and thus appear repeatedly in the structural design of high-rise buildings . However , in practical engineering , steel truss conversion layer due to the complexity of the structure and construction , the application is not a lot , is not deep enough to do experiments and research , especially under earthquake analysis is far from maturity structure of the ordinary high-rise buildings , the existing norms on such seismic design also has some limitations . In this paper, on the basis of the analysis of domestic and foreign scholars to further study the mechanical properties of the steel truss transfer earthquake storey high-rise building structures , and elastic seismic response . The first article describes some of the basic concepts and principles of design of the building structure steel truss conversion layer , and then force performance analysis of a single-layer and laminated steel truss conversion layer ; Secondly, the general theory with conversion layer construction structure elastic dynamic analysis a practical engineering background, SAP2000 finite element software to create three-dimensional finite element analysis model of the original structure by the response spectrum and time history analysis , to study the dynamic characteristics of the set steel truss conversion layer construction structure and structures under Earthquake lateral shear deformation and performance analysis of its multi- case earthquake seismic response ; then analyze the different settings of the height of the steel truss conversion layer dynamic characteristics and seismic performance comparison of different set high steel truss conversion layer structure angular displacement between the cycle and mode shapes , structural displacement , displacement layer and layer structure of shear and interlaminar shear and other aspects of performance differences .
