Analysis and Estimation of Anti-Quake Ability of Abnormity Columniation Frame Based on Pushover Method

摘要

The article makes pushover analysis for one common frame and one abnormity columnination frame. Pushover analysis on specially shaped column frames arrived at displacement between stories, yielding mode and evaluate anti-seismic capacity. On the basis of the previous researches and the special-shaped columns frame pushover results, the article analyses the influences of the axial compression ratio and the steel ratio. Besides, some practical suggestions on the design of the specially shaped column frame are proposed. This article has adopted energy method to evaluate the aseismatic capability of a regular multi-storey and multi-spanned concrete frame. The evaluation result shows that the precision can meet the needs in real constructions project.
