Analyses Of Mechanical Properties And Wind-Induced Vibration Response For Aluminum Alloy Formwork System

Aluminum formwork system is a new kind of construction formwork system, which has been put into use for many years around the world, but it is still in the early stages of exploration and research in C hina. So it is of great importance to research on aluminum formwork system.This paper investigates the mechanical properties of the Aluminum Formwork, Aluminum Alloy Frame Structure and Zhuhai C ity Garden Template Structure. Mechanica l properties analysis and wind- induced vibration response of the structure is checked by the computer simulation. First, a finite element static analysis was carried out on the standard aluminum alloy template and slab template; And then compare it to experimental results and conclusions using the theory of basic structural mechanics principle to analysis the aluminum alloy template. Calculation results show that the bearing capacity and deformation capacity of the aluminum alloy template meet the relevant norms and verify the stability of finite element analysis. Using the finite element to analysis Template for aluminum alloy frame structure, and calculate the load displacement curve of the aluminum alloy template structure, nonlinear characteristics, mechanical properties such as structural stability, and the results of analysis is consistent with experimental results.Based on this, a finite element model of Zhuhai C ity Garden Template Structure was established and the static wind response of the template system and wind-induced vibration response is respectively studied. First of all, analyze the static response of the structure. Then, the association of wind speed time series of the nodes are considered, Auto-Regressive(AR) model is employed to simulate node randomly fluctuating wind speed time series. By using programs written by simulate wind speed time series, and analysis wind- included vibration response of the template structure. The calculation results shows: the deformation occurred on the template for the most part due to wind load and the resistance to overturning and sliding of the structure resistance can be guaranteed by self- weight of template and relevant components.
