In the seismic design of curtain wall

engineers often ignore the stiffness of glass panel and only consider the mass of glass panel.The glass panel is usually equivalent to equal mass imposed on the curtain supporting structure in seismic analysis.However

the supporting structure of curtain wall will reach plastic state

and generate a large deformation under severe earthquake.So it will affect the overall stiffness of curtain wall structure in this condition.It is unknown for the effect of glass panel stiffness on the overall stiffness of complex high-rise curtain wall structure

so detailed study is needed in this field.For this problem

taking the curtain wall structure of Shanghai Center Tower as an example

the paper studies the nonlinear seismic responses of the curtain wall structure in consideration of glass panel under severe earthquake

and the results of curtain wall structure with the glass panel are contrasted with the curtain wall structure without the glass panel.It is shown that the glass panel has less impact on the main structure

but can decrease the drift ratio of curtain wall and the internal force of supporting structure.It can also decrease the acceleration magnification on higher storeys

but has less impact on lower ones.
