Abstract

The invention discloses a method and system for quickly analyzing structural parameter sensitivity of a television tower with an outer frame and an inner cylinder,and the method comprises the following steps: firstly,determining structural node information of the television tower and self-weight parameters of the structure,building an accurate model of the inner cylinder structure,and further building an equivalent model of the inner cylinder structure; on this basis,establishing an overall model of the television tower structure,and forming a mass matrix and a rigidity matrix; and establishing the sensitivity of the parameters of the television tower outer frame system and establishing the sensitivity of the parameters of the television tower inner cylinder system. By combining the sensitivities of different components,a parameter sensitivity analysis method of the television tower structure is established,a method for analyzing the frequency change of the television tower system by parameter change is established,and the frequency change of the whole structure caused by the parameter change is determined. The method has the advantages of wide application range,simple and quick calculation and the like.

Description

technical field [0001] The invention relates to a space steel structure safety assessment technology, in particular to a method and system for rapid analysis of the structural parameter sensitivity of a TV tower with an outer frame and an inner tube, which can realize the rapid analysis of the sensitivity of the structural parameters of the TV tower, which is the performance evaluation of the actual high-rise TV tower structure. provide effective means. Background technique [0002] With the economic and social development of our country, the structure of the TV tower has developed rapidly. The structure of the TV tower is an important lifeline project. It has been in service in the harsh environment for a long time, and is exposed to wind, sun and various environmental effects. Therefore, such towering space structures are prone to damage accumulation or even destruction during long-term service. In recent years, there have been many accidents of damage and destruction of...
