On the generalized variational principle of viscoelastic beam columns with damage;

Calculations of the ultimate bearing capacity of concrete-filled steel tubular beam-columns with circular hollow section;

Application of simplified softened strut-and-tie model in the design of interior reinforced concrete beam-column joints;

The following paper introduces the developing process of decorative art of architecture with wooden structure,and illustrates the decorative art of ancient architecture from door and window,caisson ceiling,beam column,flat arch and indoor furnishings,which to offer a reference for designers.

Some technical methods are used to make construction convenient when different strength grade concrete is used in the joint of beam and column in high building.

Sparging concrete has higher strength and durability,has a strong binding power with constructed concrete and concrete reinforcing bars and is used for additional strength process for beam and column of building.
