(哈爾濱工業(yè)大學土木工程學院,哈爾濱 150090)[摘要]為了研究波峰連接的受力蒙皮體的抗剪性能,在已有試驗研究的基礎上,開展了數(shù)值模擬分析。有限元分析得到的荷載和位移曲線與試驗結(jié)果吻合良好,不同受力蒙皮體的極限抗剪強度和最大剪切位移也與試驗結(jié)果基本相符,有限元分析尚可揭示連接件的剪力分布規(guī)律。[關鍵詞]波峰連接;受力蒙皮體;抗剪性能;數(shù)值模擬分析;試驗研究Numerical simulation analysis on the shear behavior of crest fixed stressed skin diaphragmZhang Yaochun, Zhang Xueli(School of Civil Engineering,Harbin Institute of Technology,Harbin 150090,China)Abstract:In order to investigate the shear behavior of crest fixed stressed skin diaphragm, the numerical simulation analysis has been conducted based on the comparing experiments. The results of finite element analysis(FEA) show that the loading versus displacement curves, the ultimate shear strength and the ultimate displacements are very close to the test results. Moreover,the shear force distribution pattern among the fasteners can be also revealed by FEA.Keywords:crest fixed; stressed skin diaphragm; shear behavior; numerical simulation analysis; experimental investigation作者簡介:張耀春,教授,博導,Email:ych-zhang@163.com。參考文獻[1]王迎.跨越多檁條受力蒙皮抗剪性能的試驗研究[D].哈爾濱:哈爾濱工業(yè)大學,2005.[2]張雪麗,張耀春.自攻螺釘波峰連接的抗剪性能試驗研究[J].土木工程學報,2008,41(6):33-39.[3]李婉瑩.跨越多檁條受力蒙皮抗剪性能數(shù)值模擬分析[D].哈爾濱:哈爾濱工業(yè)大學,2007.[4]王迎,張耀春,張文元,等.跨越多檁條受力蒙皮抗剪性能的現(xiàn)場試驗研究[J].建筑結(jié)構(gòu),2006,36(1):28-30,48.[5]張文元,張耀春,王迎,等.跨越多檁條與少檁條的受力蒙皮抗剪性能的對比試驗研究[J].建筑結(jié)構(gòu),2008,38(3):73-76.[6]李婉瑩, 張耀春,盧效哲.跨越多檁條受力蒙皮抗剪性能數(shù)值模擬分析[J].低溫建筑技術,2007,23(5):80-82.[7]李婉瑩, 張耀春.波峰或波谷連接的受力蒙皮抗剪性能數(shù)值模擬對比分析[J].工業(yè)建筑,2007,37(S1):24-27.[8]劉洋.輕鋼結(jié)構(gòu)蒙皮效應的理論與試驗研究[D].上海:同濟大學,2006.
