后张无粘结预应力平板一柱结构合理计算模式和方法的研究

RESEARCH ON REASONABLE CALCULATION SCHEME FOR UNBONDED POST-TENSIONED FLAT PLATE-COLUMN STRUCTURES

摘要: 本文通过对板一柱结构工作原理的分析和对其在竖向荷载下计算模式的回顾,利用工程力学理论,建立了后张预应力平板-柱结构在水平荷载下的合理计算模式和方法,克服了目前等代框架法中在水平荷载下内力计算与位移计算不协调的缺点,并使这种结构在竖向荷载下与水平荷载下的计算得到统一,为合理地进行结构设计提供了依据。

Abstract: By analysis of the working principle of unbonded post-tensioned flat platecolumn and review over its calculation scheme under perpendicular load, a reasonable calculation scheme for unbonded post-tensioned flat plate-column structures under horizontal load is established. The inconsistency between stress calculation and displacement calculation for equivalent-frame under horizontal load is overcome, and the calculation methods for this kind of structure under perpendicular and horizontal load are unified. This paper provides a good principle for reasonable structural design.
