Simulation of Construction Process Combining Steel Truss Integral Lifting with Concrete Pouring for SRC Conversion Layer Structure

摘要

The steel reinforced concrete structure is widely used in the large space structure with its excellent mechanical properties, superior economic performance and outstanding comprehensive benefit. This type of structure is a combination of structure, section steel, steel bar, concrete and other components, due to the construction sequence is not the same, the secondary stress in the structure will not be the same, the safety of the construction process will be different. In this paper, we put forward the whole lifting of the steel skeleton, and then put the concrete into the layer by layer, forming the steel reinforced concrete structure. The method has the advantages of convenient construction, short construction period, and can save a lot of cost, and need to simulate the construction process. In this paper, the construction process of the integral lifting construction of the steel reinforced concrete structure is studied in detail, then, the analysis of the structure of the steel truss lifting and load transfer process is studied. In the process of pouring concrete, the support structure is analyzed, and finally the stress process of steel reinforced concrete structure is analyzed. The research results show that the integral lifting construction method of the steel reinforced concrete structure can ensure the safety of the structure.
