［摘要］ 波形鋼板組合墻由雙層波形鋼板、內(nèi)填混凝土以及對(duì)拉螺栓組成，具有良好的受力特性。對(duì)波形鋼板組合墻中對(duì)拉螺栓極限狀態(tài)及極限狀態(tài)后的受力機(jī)理進(jìn)行了分析。通過理論推導(dǎo)得到螺栓拉力的理論公式，從中提煉影響較大的重要參數(shù)。在此基礎(chǔ)上建立精細(xì)化有限元模型，通過有限元結(jié)果與試驗(yàn)結(jié)果對(duì)比，得到與試驗(yàn)結(jié)果更加吻合的有限元模型，并用于參數(shù)分析。最終通過數(shù)值計(jì)算，得到波形鋼板組合墻對(duì)拉螺栓拉力的設(shè)計(jì)公式。

Abstract: Concrete-infilled double steel corrugated-plate wall (CDSCW) is composed of double steel corrugated-plate, infilled concrete and split bolts between them, which has good mechanical performance. Mechanism of split bolts of CDSCW was studied in its limit state and post-limit state. Through theoretical derivation, the theoretical formula for predicting the tensile force of the bolts was conducted and some important affecting parameters were derived. Refined finite element model (RFEM) for simulating the bolts and CDSCW was established based on a series of comparison between FEM results and test results and was used for parameter analysis. Finally, design formula for estimating the tensile force of the bolts was established based on numerical investigation of the RFEM. 

Keywords:concrete-infilled double steel corrugated-plate wall； split bolt； mechanism； design method
