Research on Displacement and Stability of the Tapered Member;

This method is used to derive the deflection of variant cross-section members which are composed of multiple segments of tapered members.

At the same time, tapered members which have appropriate section properties are widely used in that kind of structures.

Study of effects of longitudinal to shear bearing capacity of high-strength concrete beam-column via finite-element analysis and experiments;

Design of tapered Ⅰ-section arc-shaped beam-column with holes in web;

Second-order vibration analysis of beam-columns;

Analysis of the buckling reliability of the beam column;

Load-deformation relationship curves of steel tube beam columns with rhombic sections are calculated by the ABAQUS software,and the calculated main parameters are steel yield strength and load eccentricity.

Based on catastrophe theory, the paper establishes cusp catastrophe model of instability of simply supported beam column.

The buckling calculation for compression-bending members of concrete-filled rectangular steel tube is the best important in《Technical specification for structures with concrete-filled rectangular steel tube members》.

In this paper, a set of design methods on the compression-bending members in line with the up-to-date code of China are presented, on the basis of fire-resistant experimental research and theories in China and foreign countries.

In this paper, the research current situation at domestic and abroad and existing main research theory of CFST component is introduced, and M-φ hysteretic capability of CFST compression-bending member is resear.
