This paper presents methods for detail handling of small -angle supporting joints.

Analysis of ratio of axial compressive force to resisting shear strength of reinforced concrete beam-column joints;

Research into fracture of steel frame beam-column joints;

The influence factor to the ultimate bearing capacity of concrete beam-column joints with placed ducts under axes-pressure;

The seismic resistant design method of reinforced concrete beam-column connections based on compression strut and softened truss models;

Therefore, the study on the behavior of the beam-column connections to improve ductility as well as to prevent brittle failure was carried out in this research.

Three-dimensional finite element method was employed toinvestigate the effect of the strength mismatching of the groove heamflange welds on the fracture toughness requirements in terms of crack tipopening displacement in welded beam-column connections, which pro-vides valuable suggestions for the design of beam-column connections andselecting welding materials.

Load capacity and stiffness of beam-column joint strengthened by plate rings with irregularly arranged double level beams;

Studies on shear performance of reinforced concrete beam-column joint strengthened by a new method with two-dimensional finite element analysis;

Studies on failure mechanism of reinforced concrete beam-column joints using three-dimensional finite element method;
