Abstract:

The method of collaborative work between steel plate anti-wind bearing (AWB) and rubber isolation bearing is proposed to study the vibration reduction effect of isolation structure under stronger wind load, and the function mechanism is explained. Based on a practical project, three kinds of schemes with different isolation layers are put forward, the finite element software ETABS is used for time history analysis, and comparison is made on the seismic response of different isolated structure and aseismic structure. Comparison result shows that the isolation layer with rubber bearing and AWB can work reasonably, but further optimization on the designed parameters is needed. Moreover, the design value of horizontal bearing capacity of lead rubber bearing (LRB) is appropriate to be close to the seismic isolation layer under wind load excitation. Finally, numerical simulation and comparative analysis of shear test of the AWB are conducted. With a very small yield displacement and yield strength over 80% of the set of horizontal bearing capacity, the AWB is validated to satisfy the working conditions which provide the horizontal bearing capacity under normal operating conditions and designed earthquake. The AWB yields and malfunctions, when the maximum displacement is less than the displacement of the isolation layer. © 2016, Shanghai Jiaotong University and Springer-Verlag Berlin Heidelberg.
