Abstract

In order to study the displacement response of the attached lifting scaffold under the action of fluctuating wind, this paper combines the harmonic synthesis method and Kaimal wind speed power spectrum to simulate the fluctuating wind in time, and uses the Newmark-β method to solve the displacement response of the attached lifting scaffold under the action of fluctuating wind load, and analyses the stability of the attached lifting scaffold by comparing the displacement response under the action of fluctuating wind load and static wind load to provide a reference basis for practical engineering. The results show that the top middle of the attached lifting scaffold is the weakest position, and that the displacement response of each node under the action of fluctuating wind load is greater than the displacement response under the action of static wind load. In order to achieve the displacement response bearing value under the action of instantaneous wind load, it is recommended to carry out dynamic analysis in the design verification of actual construction to avoid unsafe measures in actual use.
