Abstract
A new long-span space grid structure system, “single-layer folded space grid” (SFSG), is applied in the Shenzhen Universiade Stadium. Compared with regular single-layer grid, the out-of plane stiffness and bearing capacity of the structure is improved with bending and uplifting of the structural units in SFSG, and the span capacity of the structure is then enhanced. Because of the large structural dimension, the construction process including assembling, closure and brace-unloading should be divided into many stages. As a result, there is very strong time-dependent effect for the structural stress state in construction. In this paper, based on matrix mechanics model of space grid structures, a time-dependent analysis method considering temperature variation during construction is presented based on matrix mechanics model to optimize the closure scheme. A combined brace element is presented to accurately simulate the mechanic character of temporary braces. In this way, the whole construction process of assembling, closure and brace-unloading are effectively and accurately analyzed for the SFSG structure of Shenzhen Universiade Stadium. The displacement state, stress distribution, and force changes in temporary braces are obtained to provide instruction for the design and control of construction process.
