Numerical analysis on a new type cross-shaped frame joint of steel reinforced concrete special-shaped column

摘要

In order to facilitate the construction, this paper presents a new type of cross-shaped frame joint of steel reinforced concrete special-shaped column, and the cross-shaped frame joint of new type of specially-shaped column is the regular concrete joint which is added acre steel-shaped steel. Numerical analysis is conducted on a regular concrete cross-shaped frame joint of specially-shaped column of a frame structure in the region with intensity 8 of Chinese intensity scale, and the joint of corresponding new type of specially-shaped column of the same structure, to obtain the conclusion that when the new type of cross-shaped frame joint of steel reinforced concrete special-shaped column is 6% in steel ratio, the ultimate bearing capacity of joint relative to the RC nodes can improve 34.5% which shows that the cross-shaped frame joint of new type of specially-shaped column can not only has the advantages of convenient construction, accelerate the construction speed, and the shear capacity also has safeguard.
