The Economical Performance Analysis Of Staggered Truss Structures

Staggered truss structure has seen a worldwide renaissance because it can yield great economy and maximum architectural and planning flexibility. The dissertation has adopted the designing soft of PKPM to analyze the designing method of 130 modes of staggered truss structures at 7 degrees seismic fortification intensity. Through the analysis of these modes, the dissertation has obtained the ratio of every moment to the whole structure and quantitatively analyzed the miscellaneous factors which may influent the economic performance of staggered truss structure and then analyzed the composed moments of the value of staggered truss structure. Then through the compare with R.C. structure, this paper explored the economic benefits and the social benefits. The dissertation has mainly completed these as follows:(1)With the macro-scale designing software of PKPM, the dissertation has directly applied the current designing codes of our country to analyze the designing method of staggered truss structures and presented the designing process and the calculating principle of staggered truss structures in details, and also fully explained the core controlling parameters needed for the design of staggered truss structures.(2)50 twelve stories of staggered truss structures and 80 six stories of staggered truss structural models of 7 degrees anti-seismic districts, has been designed to analyze in this paper. Through the calculation of the used steel quantity, the dissertation has analyzed the used steel quantity proportion of each composition component to the whole structure. The analysis shows that truss used steel quantity is the major element what decides the whole cast of the structure and the ratio of column and truss used steel quantity to the whole between multistoried and high-rise...
