**摘要**：本文讨论了由焊接凝灰岩砌体和木框架建造的历史建筑结构。这种木 - 砌体复合结构于20世纪初左右在日本建成。木框架由立柱和圈梁组成。立柱通过榫卯节点与贯穿的圈梁相连。立柱通过L形锻铁栓钉与砌体墙连接。本文以一座仓库作为案例研究。进行了拔出和剪切试验以检验砌体墙与立柱之间节点的性能。重点关注了铁栓钉的作用。对案例建筑进行了微震测试。基于这些试验活动，通过数值方法进行了抗震分析。重点关注了砌体墙与木立柱之间节点行为的离散化。本文从结构上介绍了一座独特的历史建筑，并讨论了其抗震性能，重点关注了由铁栓钉和榫卯节点所产生的节点行为。研究结果可用于历史复合结构的抗震分析。
ABSTRACT The paper discusses heritage structures built of welded tuff masonry and timber frames. Such timber-masonry composite structures were built in Japan around the early 20th century. Timber frames are composed of studs and girts. The studs are coupled by penetrating girts via nuki joints. The studs are connected to masonry walls by means of L-shaped wrought iron pegs. In this paper, a warehouse is considered as the case study. Pull-out and shear tests were conducted to examine the performance of joints between a masonry wall and stud. A focus was given to the contribution of iron pegs. A microtremor test was performed on the case study. Based on these experimental activities, seismic analysis was carried out by numerical approach. Attention was paid to the discretisation of joint behaviour between masonry walls and timber studs. The paper introduces structurally a unique heritage building and discusses its seismic behaviour, focusing on joint behaviour derived from iron pegs and nuki joints. Findings are taken advantage of for the seismic analysis of historical composite structures.
