The Wind Vibration Response Analysis Of The Adhesive Integral-lift Scaffold

With the development of society,more and more high-rise buildings in real life.As a kind of indispensable construction equipment in the construction engineering,the attached lifting scaffold,in the rapid economic development of today’s society,its security and reliability has become inseparable with people’s lives.Attached type lifting scaffold as a frame construction by the steel tube of the tool when attached lifting scaffold in the construction process,the influence of wind power has become a problem that can not be ignored.The height of the building is higher and higher,and the attached lifting scaffold needs to be elevated to the corresponding height to meet the construction requirements.In order to ensure the safety of construction workers and the reliability of the attached lifting scaffold,it has become more and more important to carry out the correlation analysis of the displacements of the joints under the wind.The research object of this paper is the attached lifting scaffold used in the construction site of Gansu construction investment seven construction group.The dimensions of the attached lifting scaffold and the properties of the material are measured.The finite element model is established by using the corresponding software.Based on the relevant codes and the time history simulation of fluctuating wind,the simulation of fluctuating wind speed time history and the displacement response simulation of the attached lifting scaffold.The contents of this paper include the following:Set up by the analysis software according to the size and material properties known to be attached type lifting scaffold model,and analyze the correlation of attached type lifting scaffold model by the software,so as to obtain the inherent characteristics of attached type lifting scaffold model(vibration frequency,vibration type etc.).So as to get the influence of the foundation stiffness on the attached lifting scaffold structure.The advantages and disadvantages of different methods are obtained through the introduction of wind load simulation method.Select the corresponding wind speed spectrum as the target spectrum,and the feasibility of the strong analysis method,using programming software in the simulation of the necessary procedures.The effect of the wind on the attached lifting scaffold has been simulated by the compiled program.According to the resultsobtained,the time history curve of the attached lifting scaffold has been known.By using the corresponding theoretical formula,the time history curve of the effect of wind on each node of the attached lifting scaffold is obtained,which provides a theoretical basis for the study of the relative displacement of the attached lifting scaffold.According to the basic theory of the income,and analyze the corresponding response of the lifting scaffolding frame structure attached by related analysis software,in order to get the displacement curve of the corresponding node of the attached type lifting scaffold.It provides the basis for future design and application.
