Elastic dynamic characteristics analyses of flange frame column structure with different length flange components were carried out,and the distinguishing principle which this type of component was designed as frame column or shear-wall was given.

According to the problems in structural design of underframe, it analyzes the problems should be noticed including sample of bottom height?layout of quake-proof wall?ratio of rigidity?edge member and introduces right means to settle the problems.

This article , combined with a practical project design ,analyzes the distortion characteristics of column supported sheer-wall structure of high-rise buildings ,and concludes a method to calculate the bend yield and the utmost yield of a structural member ,in view of the functions of concrete and steel bar of edge member .

The requirements for edge member steel and vertical distribution steel of each wall segment are considered during steel arrangement.

The Property Evaluation and Manufacturing Technology of Full Size Flange and Web Made of Larch Veneer Material for I-joist Purpose;

The influencing of the steel quantity by considering the PRC frame flange;

Crack resistance of RC joints with specially shaped columns considering the effect of flange length

The structure, manufacturing process and forming conditions of the thermoset injection mould used for mass production of the insulation fabric parts of PT_610 special plastics were introduced.
