Mechanics Analysis and Construction Measures on Tension-Chord Beam Architecture

Abstract:

In order to acquire mechanic performance of tension-chord Beam structure and the interaction between column and soil for canopy structure, combined with its own particularity pipe-soil ANSYS nonlinear analysis was carried out by using DP model, and from buried depth of pipe variation law of deformation, shear stress and equivalent stress for surrounding soil was investigated. The results show that the vertical stress is the bigger than horizontal stress and local stress of soil under pipe is larger, so this phenomenon is regarded as the stress concentration. Flexible connecting of column bottom can realize movement and recombination of structure, and pipe-soil radius and construction measures can provide safe and reliable reference for design and construction of mobile greenhouse structure.
