Wind load is one of the main lateral control loads that need to be
considered in the design of high-rise building structures. It is also of great
engineering significance to study the influence of static wind load or
time-varying wind load on the dynamic response of structures. In this paper, a
high-rise building with a rectangular section (46.8 m × 27 m × 33 m) is
simulated based on Ansys18.0 APDL software. The real situation of its response
under no lateral wind load and different fluctuating wind load conditions is simulated
and the stress and strain response of the building under steady-state and
time-varying wind load is given. The results show that the upper strain of the
structure under wind load is about 1/1000 of the bottom strain, and the strain
of the structure shows obvious accumulation from the top to the bottom, that is,
the bottom strain of the building will be higher than the top strain. The
influence of time-varying wind load on building structure is related to the
loading position of wind load on the structure. The results provide a basis for
the structural wind resistance design of this type of building.
