Influence Analysis Of Different Parameters On Static Dynamic And Elastic-Plastic Stabilization Performance Of Suspen-dome Structure

Suspen-dome is a new self-equilibrium space structure , composed of single-layer lattice shell and cable-strut tensile structure. Its static and stabilization performance is the key to structure'implematation, Every influencing aspect is the most significant part. research on every parameters'influence is not only help master the structure'advantages and disadvantages, but also offer credible rule for construction and design. First this essay deliberates the nonlinear analysis approach. Based on research of suspen-dome's static nature with ADINA, we study on five parameters'impact on static nature, including endless rope prestress , poling length, pole section, ratio of rise to span, mesh format and compare the inner force, displacement and bearing reaction of classic element; According to the analysis of elastic flexion, we study on elastic and plastic stabilization, get the limit load and analyse the above five parameters'impact on stabilization; Then study on shaking model , achieve autooscillation frequency and mode and analyse the above five parameters'impact on autooscillation frequency; Finally , analyse seismic response of cross direction , get temporal curve and then draw a conclusion.
