本文讨论了 NSF/NEES 资助的 NEESWood 项目中正在进行的全尺寸两层木结构联排别墅的振动台测试项目。该测试建筑代表了在振动台上测试的世界上最大的木框架结构。测试结构的尺寸和重量需要同时使用布法罗大学结构工程和地震模拟实验室的两个三轴振动台。测试计划重点关注可能对木框架建筑的地震响应产生重大影响的各种建筑元素，并且在基于性能的抗震设计中应考虑这些元素。本文重点讨论石膏墙板饰面的效果。迄今为止获得的结果表明，应用于结构（承重）墙内表面的石膏墙板饰面的影响显着改善了测试建筑物的地震响应。另一方面，应用于内部隔墙的相同石膏墙板墙饰面对测试建筑物的地震响应没有有益影响，因为这些隔墙与相邻地板和屋顶隔板之间缺乏结构连接。
This paper discusses the on-going shake table testing program on a full-scale two-story woodframe townhouse building conducted within the NSF/NEES-funded NEESWood Project. The test building represents the worlds largest woodframe structure tested on a shake table. The size and weight of the test structure required the simultaneous use of the two tri-axial shake tables in the Structural Engineering and Earthquake Simulation Laboratory at the University at Buffalo. The testing program is focusing on the various construction elements that may have significant influence on the seismic response of woodframe buildings and that should be considered in performance-based seismic design. This paper focuses on the effects of gypsum wallboard finishes. The results obtained so far indicate that the influence of gypsum wallboard finishes applied to the interior surfaces of structural (load bearing) walls substantially improved the seismic response of the test building. On the other hand, the same gypsum wallboard wall finishes applied to interior partition walls had no beneficial effect on the seismic response of the test building because of the lack of structural connections between those partition walls and adjacent floor and roof diaphragms.
