Design and Analysis of Steel Structure of the Teaching Building of Beijing Future City School
The above-ground part of the teaching building of Beijing Future City School adopts a steel frame structure,and the peculiarly shaped teaching building is divided into three parts by setting two structural joints.The underground part of the teaching building adopts a reinforced concrete frame structure without structural joints.The steel corridor has a span of 33 m and adopts a two-story full-height truss structure.The steel corridor is weakly connected to the main structures on both sides.By comparing the three load bearing schemes,the metal friction pendulum isolation bearing and viscous fluid damper is selected.Dynamic elastic-plastic time-history analysis is carried out on the overall modeling of the steel corridor and the main structures on both sides.The whole corridor acts as a rigid object to respond to the earthquake with the three-story main building,and the isolation effect of the isolation bearing is remarkable.This paper introduces the precautions for the connection joints between reinforced concrete beams and steel reinforced concrete columns and beam reinforcement,which provides a reference for related engineering design.
