ANALYTICAL STUDY ON SEISMIC PERFORMANCE OF THE STRUCTURE OF HIGH-LEVEL TRANSFER WITH ENERGY DISSIPATION DEVICES

摘要

In this paper, a structure of high-level transfer with huge girders is taken into consideration. It analyzed the traditional structure of high-level transfer and the structure of high-level transfer with energy dissipation devices models in which the floors (not including the transfer story) are simulated under the postulate of rigid floor and elastic floor. The analysis could be concluded as following: firstly, the internal forces of transfer beams with the assumption of rigid floor are greater than those with the assumption of elastic floor, while the shear wall stresses are exactly opposite; secondly, the shear wall stress of the structure of high-level transfer with energy dissipation devices is obviously reduced whether the floors are rigid floor model or elastic floor model; thirdly, the scheme that the transfer story adopts the assumption of elastic floor and other stories adopt the assumption of rigid floor is feasible to conduct the structure of high-level transfer with energy dissipation devices analysis. Those research results will offer some referential information for the application of the structure of high-level transfer with energy dissipation devices.
