Weighted generalized inverse method for topological modification of frame structures;

The stochastic finite element controlling equation of frame structure is deduced.

Aiming at the insufficient research of reliability analysis on stiffness for system,the method of continual variation on stiffness for frame structure is derived.

Application of genetic algorithm in optimization design for random parameters rigid frame structures;

In this papcr, the special fcatures of the internal forces and the dcformations of rigid frame structures with inclining columns are analysed.

The metal rigid frame structure bears most of the weight of the escalator.

In the method of curved bar units, a arch dam is seperated into space rigid framed structures and curved bars are taken as the basic units of calculation.

Geometric constitution of space frame structure based on space-filling polyhedron;

The design of the foundation of portal frame structure under special foundation condition;

This paper discusses modeling method of finite element about large span portal frame structure in a certain workshop,and performs the non-linear static analysis of this structure by using ANSYS.

In China, with the fast economic development rising, portal frame structures with profiled steel sheets as maintenance system and H type steel members as main frame demostrates great market interests in the field of industrial and civil constructions.
