[摘要]基于部分剪力連接模型,利用結(jié)構(gòu)力學(xué)的基本原理,同時(shí)考慮了各種因素的影響,對不同工況作用下的連續(xù)組合板的極限承載力計(jì)算方法進(jìn)行了推導(dǎo)。與國內(nèi)外的連續(xù)組合板試驗(yàn)結(jié)果的對比表明,提出的計(jì)算方法能夠較為準(zhǔn)確地計(jì)算連續(xù)組合板的極限承載力。通過改變不同的參數(shù),對影響連續(xù)組合板極限承載力的主要參數(shù)進(jìn)行了分析,提出了實(shí)際工程中宜遵循的原則。最后給出了實(shí)用的設(shè)計(jì)表達(dá)式。

Analysis of ultimate capacity of continuous profiled steel sheet-concrete composite slab based on partial connection model

Abstract:Analysis of the ultimate capacity of continuous composite slab is made based on partial connection model and principle of structure mechanism. Variable load conditions and parameters are considered. Comparisons between experimental results and theoretical results show that the proposed method is accurate for calculating the ultimate capacity of continuous composite slab. The main effects on ultimate capacity of continuous composite slab are analyzed by changing variable parameters. Some proposals are advised for practical design and the design method is proposed.
Keywords:continuous composite slab; profiled steel sheet; ultimate capacity; partial connection model
