Mechanics Performance Research Of Specical-Shaped Reinforced Concrete Columns Frame Structure

The R. C. special-shaped columns frame structure is one kind of new residential building which has only been researched in the recent 20 years. This type building is filled with lightweight material filler-walls which make it lightweight, heat-preservation and benefit to the anti-seismic design. In the practical engineering, the frame-structure with special-shaped columns has obtained great society and economic benefit. This kind of structure has been popular used in Guangzhou, tianjin and shanghai etc. The practice proved that the special-shaped columns frame structure has so many advantages such as being changed easily, economical and low price, what more, Its residential environment is better than normal R. C structure and the space can be take efficiently advantage of .This paper take advantage of finite-element method analytical software ANSYS which has powerful function. In this paper, it contrastive analysis dynamical characteristic of The R. C. special-shaped columns frame structure and rectangular columns frame structure by using building 3-D spatial analysis model, contrastive analysis transformative characteristic and distributing rule of internal force of special-shaped columns framemethod and contrastive analysis transformative characteristic and distributing rule of internal force of special-shaped columns frame structure and rectangular columns frame structure by history domain method when they are under earthquake effect, finally, this paper analysis force characteristic of special-shaped columns frame structure and L~type columns by building 3-D entitative finite element model which are under horizontal force and some important conclusions on force characteristic of special-shaped columns frame structure are reached. The conclusion of this paper can be consulted and applied by engineering design.
