New technology used in welding of construction steel structure;

Quality control and test of T-joint and angle welded joint in construction steel structure;

Analysis on development tendency of coatings for environmental protection construction steel structure

The high strain low cycle fatigue properties of V Ti micro alloyed high anti seismic structural steel were studied with simulated earthquake loading.

This paper introduces the characteristics and types of building steel structures; mainly narrates the design for the protection painting of building steel structure; and discusses the common problems in protection painting systems.

The paper introduces the rust preventing primer, face paint and fire-retarding paint for building steel structure.

The present situation of steel building at home and aboard is introduced,merits of steel building and beneficial conditions to develop steel building in China are discussed,it is pointed out that steel building is developing direction of China building industry in the future.

It is the same with all the steel buildings design and construction.

At present, the domestic codes/specifications for the inspection and appraisal of steel building structures are not sufficient for practical reference, which may become one of the encumbrances to the rapid development of the steel structures.

In this paper,with a brief review on the development history of steel building structures of China,the current development status of the steel building structure industry was summarized,the necessary and urgent requirement to promote the development of steel building structure industry in China was established,and the opportunity and existing problems with this important issue were discussed.
