钢管高强膨胀混凝土的数值模拟

Numerical simulation of high-strength expansive filled steel tube concrete

钢管高强膨胀混凝土是一种新型结构形式,适用于岩土工程、地下工程、桥梁和高层建筑。应用结构分析有限元软件,将钢管高强膨胀混凝土视为非均质材料的组合结构,分别建立钢管和核心膨胀混凝土柱模型,对强度和膨胀剂含量不同的钢管混凝土进行数值模拟。数值模拟结果与相应实验结果较为一致,表明数值模拟分析钢管高强混凝土混凝土这种界面的组合结构十分有利。

The high-strength expansive filled steel tube concrete is a kind of new-type structure form.This form is suitable for geotechnical projects,bridge and tall buildings.By using structural analysis finite element software,the high-strength expansive filled steel tube concrete is regard as combining structure of non-homogeneous material.For the steel tube and core concrete,their models are established separately.The steel tube concrete of the content of pharmaceutical carries on the numerical simulation to different intensity and inflation.Numerical simulation result and corresponding experimental result are comparatively unanimous.
