This paper presents the results of shake table tests and periodical friction tests to evaluate the dynamic and long-term performance of a novel connector using a wood friction (friction-based connectors). The friction-based connectors are a quite simple system in which the wood is bolted transversely to generate friction force. The shake table tests showed that the type of hysteresis loop of the wall with the friction-based connectors exhibited a bilinear, and significantly reduced the maximum response displacement even when the conventional walls were combined. In addition, more than 60% of the total energy was absorbed by the wall with friction-based connectors, even the load bearing ratio of the wall was about 30%. The periodical friction tests of the connectors and the wall with the friction-based connectors indicated that the friction forces were mostly linked to the relaxation behavior of wood, and although the friction forces were significantly affected by humidity fluctuations, long-term friction forces were expected to be maintained.

木材剪力墙用木材摩擦连接器的动态和长期性能

本文介绍了振动台测试和定期摩擦测试的结果,以评估使用木质摩擦的新型连接器(基于摩擦的连接器)的动态和长期性能。基于摩擦的连接器是一个非常简单的系统,其中将木材横向栓接以产生摩擦力。振动台测试表明,具有基于摩擦的连接器的壁的磁滞回线的类型呈现双线性,并且即使将常规的壁组合在一起,也显着减小了最大响应位移。此外,带有摩擦连接器的墙体吸收了总能量的60%以上,即使墙体的承重比约为30%。
