Design and application of the damp shroud featuring equal strength and small loss;

Bolt with full screw threads and equal strength is a new type of bolt.

According to the equation of shrunk interface pressure and the condition of diametrical ratio based on the theory of equal strength, it is found that the diametrical ratio does not conform to the condition of diametrical ratio, and the distribution of stress is very non-uniform.

The flexural rigidity optimal distribution of the equi-strength static-indeterminant beam under a concentrated force is studied.

The volume optimal design of an equi-strength two degree static-indeterminant beam subjected to a concentrated force and geometry constraint is studied by means of the stepped reduction method.

Study of equivalent strength for bilateral interval crack director of RCC arch dam;

Size effect on equivalent strength and fracture toughness of RCC with pre-induced penetrated crack;

Calculation model of equivalent strength for induced crack in RCC arch dam based on double parameter fracture theory;

When using equal strength beam to calibrate fiber Bragg grating(FBG)strain sensor,the thickness of encapsulation slice(or diameter of encapsulation steel tube)will affect the calibration result because of bend distortion of equal strength beam.

The comparison relation about concrete intensity grade standard have been talked about the advantages of high intensity concrete and main the differences from ordinary concrete have been given a brief introduction.
