SEISMIC-REV Reduction of Earthquake Vulnerability Seismic-REV 项目(降低地震易损性)的明确目标是通过研究并阐明木结构建筑装配所用的传统金属连接件的性能,降低木结构 的地震易损性。另外,还提出了名为 X-RAD 的创新连接系统,该系统用于住宅 CLT 建筑(正交胶合木,即由相互垂直排列的多 层板制成的木板)。此研究项目涉及不同机构。Rothoblaas 与 CNR-IVALSA Institute of San Michele all’Adige (圣米歇尔阿迪奇 CNR-IVALSA研究所) 和 University of Trento(意大利特伦托大学)合作,在这两家机构开展了实验和研究工作。 关于实验测试的科学报告可从 Rothoblaas 获取。 连接件(螺钉、钉……) 圆柱形连接件(例如螺钉和钉),可承受拉力和剪力,适用于木-金属板、钢-木以及木-木节点。 1 2 经过剪切荷载测试的盖板-框架 试件,带环形钉子 3 经过剪切测试的钢-木试件,带 LBS 螺钉 经过张拉和压缩组合测试的木木试件,带 VGZ 倾斜螺钉 1 25 25 15 20 10 5 0 经过剪切测试的木-木试件,带 HBS 螺钉 2 30 20 force [kN] force [kN] 4 -5 15 10 5 0 -10 M_OSB2,8x80 -15 C_OSB2,8x80_1 -5 -10 -20 -15 -10 -5 0 5 10 15 20 25 35 0 2 4 6 8 10 12 14 16 18 displacement [mm] displacement [mm] 3 40 4 30 35 20 10 25 force [kN] force [kN] 30 20 15 0 -10 10 M_HBS10x160 -20 5 C_HBS10x160_2 -30 0 0 1 2 3 4 5 6 displacement [mm] 172 | SEISMIC-REV | 金属和建筑节点 7 8 9 10 -40 -30 -20 -10 0 10 displacement [mm] 20 30 40
