Abstract:In the structural design of part A of Qingyuan Science and Technology Museum and Youth Activity Center, steel truss and unbonded prestressed slab were applied to meet the architects′ requirements of large span and wide space. In addition, according to the construction simulation, the stress of the structure of each stage was analyzed, which ensured the feasibility of the whole process of the scheme. Finally, the comfort degree of the large-span area was analyzed, and it was verified that the peak value of vertical vibration acceleration of the floor could meet the requirements of the code.

Keywords:steel truss; unbonded prestress; construction simulation; comfort degree
