So in the analysis model of frame structures,the rigid region should be set on all rigid ends of the beam,as a result the more reasonable calculation span of frame beam can be used for structure analysis to make the control section consistent with the calculation section of the beam.

Design of steel-aluminum composite section member in curtain wall construction;

It also puts forward the problem to be paid attention, when analyzing elastic foundation slab, hybrid structure and compound section with multi-material and cable structure.

In this paper, advanced integral theory and computer are applied to solve the stress distribution of steel-concrete compound section.

A general model and its heuristic algorithms are presented for engineering structures with discrete variables and built-up sections, where all design variables in a section are combined into one design variable, and restrictive conditions according to the effect ranges are classified into three types, local, global and medium.

The Prestressed RPC-NC combined section beams have good performance in durability and economical efficiency;however, the present specifications have not provide a valid and effective calculation method specially to prestressed RPC-NC combined section beams.

With the help of the ANSYS,the bending effect under Uniform Load of the thin walled aluminum alloy combined section beam have been calculated by adopting three methods from simulation to predigestion.
