Abstract


Hanging hanging cable arch structure is composed of structures and cable arch structure combined into a hybrid structure system that utilization of a variety of different structures in terms of performance, economic indicators and other advantages, both to meet certain requirements and architectural aesthetic greater economic rationality can span across. This will be an actual project as a model to study analyzed the main cables in hybrid architecture and force structure prestressed cable on performance, their work performance and construction issues, the conclusions for the further promotion of such structures provide theoretical basis. This paper first reviews the hanging structure, cable arch structure and hanging cable arch structure development and research status at home and abroad, and then relying on an engineering example, the establishment of a hanging cable arch structure of the finite element model. Through the process of cell death function simulates the hanging roof, roof arches and arch roof cable mechanical properties, in order to search arch and hanging roof structure were compared. Because the structure to withstand static load is the most common one of the most important loads, so this article in static areas: comparison of the structural buckling capacity, buckling performance, internal force distribution and a key element of the structural stress to analyze stayed Faso and prestressed cable on the structural properties of the force and their work performance. In order to avoid wind-induced vibration and other structures in the earthquake damaged under dynamic loads, so the paper analyzes the structure of the dynamic performance: comparing the vibration characteristics of each model - frequency and vibration analysis and prestressed cable for cable-stayed structure vibration characteristics; Comparison of the structure model under seismic loads in the time course of the displacement reaction, analysis and prestressed cable for cable-stayed structure seismic performance. In the right structure for seismic response analysis using time history analysis method, the input seismic waves, including two post-equivalent seismic waves and one artificial seismic waves. Which is the use of artificial seismic waves synthesis trigonometric series self programming with MATLAB fitting standard response spectrum obtained. For this role because there is a steel cable with mercy soft hybrid structure, the construction program for the final shape of the structure and safety is essential, so the end of this article for hanging cable arch roof construction simulation carried out, stayed mainly studied cable construction sequence and the final shape of the structure of the force. Stay cables hanging cable arch structure is the main component of the force, prolonged exposure to the atmosphere, so this also stay cable corrosion are discussed.
