For researching principle and production line state of steam curing of composite wallboard, the art have been conducted through actual investigation and field test. Based on the influence of steam curing on the strength of high performance concrete, durability and volume stability, put forward suggestions of steam curing system; Several problems have been raised for steam curing in the actual production, then some correlative improve measurements are given. Provide the reference for the production and development of the residential part in our country.

Take composite wallboard of residential parts as object of study, use investigation and theoretical calculation to check unfavorable conditions of Mold-unloading-lifting and lifting-transportation in industrial production. mold-unloading coefficient and dynamic coefficient value are researched according to summarize domestic and foreign standard, and give out suggested dynamic coefficient values of construction checking of lifting-transportation for composite wallboard. It can provide reference of production and development of residential parts.

To study the influence of slenderness on the compressive bearing capacity of autoclaved fly ash perforated brick masonry long columns and provide experimental evidences for making corresponding technical code, compression tests were conducted on 9 autoclaved fly ash perforated brick masonrys long columns of different slenderness. The damage patterns and compression performance are analyzed. The experimental results indicate that compressive capacity decreases proportionally as slenderness increases and the proposed formula of axial compressive bearing capacity for autoclaved fly ash perforated brick masonry columns is given. The nonlinear FEA program ANSYS is also adopted to simulate the behaviors of masonry columns. By comparing results find that the simulated results agree well with the test ones, the rationality and applicability of the model are verified.

Two computer models of concrete frame with staircase were made and the seismic-performance of the models in elastic-phase was calculated by adopting base shear method, spectrum analysis by ETABS. The results show that including staircase into models will change the seismic performance of frame structure significantly. The paper proposes that the computer model with staircase and the response spectrum analysis should be used firstly in the seismic design of concrete frame with staircase.
