【摘要】：針對當前土木工程建筑中用到的鋼管混凝土結(jié)構(gòu)存在鋼管與混凝土脫空率較高,不能有效發(fā)揮出鋼管和混凝土的優(yōu)勢這一核心問題,結(jié)合某工業(yè)建筑中鋼管混凝土配合比研究,優(yōu)化考慮了鋼管與混凝土之間的黏結(jié)行為,采用了基于C60混凝土作為基本材料,進行了配合比的優(yōu)化研究,獲得了一類優(yōu)化的配合比數(shù)據(jù)。經(jīng)過實際工程的檢驗和力學試驗分析,表明此類配合比滿足工程需求,具有強度高、填充性能好、收縮率低等優(yōu)點,對于在同類鋼管混凝土工程中運用,有重要的工程價值。
[Abstract]:In view of the core problem that concrete filled steel tube (CFST) structure used in civil engineering buildings has a high void ratio between steel tube and concrete, which can not effectively bring the advantages of steel tube and concrete into full play, this paper studies the mix ratio of concrete-filled steel tube (CFST) in a certain industrial building. The bonding behavior between steel tube and concrete is considered in this paper. Based on C60 concrete as the basic material, the optimization of mix ratio is studied, and a class of optimized mix ratio data are obtained. Through the examination of practical engineering and mechanical test analysis, it is shown that this kind of mix ratio meets the engineering requirements, has the advantages of high strength, good filling performance and low shrinkage rate, and has important engineering value for the application of similar concrete filled steel tube projects.
