Timber, as a renewable material, has the potential to be material of construction of low-rise as well as high-rise buildings. The wood's market share is the lowest in the construction of such buildings in comparison to other construction materials. There are several heavy timber structural systems, such Cross Laminated Timber (CLT), Nailed Laminated Timber (NLT), Glulam Rigid Frames, Glulam Braced Frames, and Hybrid Girders. However, no detailed study has been done to assess the behaviour of different heavy timber structure systems under wind loads, and also no accurate and yet simple analysis and design tools are available to handle the structural design of such buildings. The final objective of this research program is to develop comprehensive guidelines as well as tools that can be used to analyze and design different heavy timber structural systems. The current study is the first step to achieve the final objective by assessing the behaviour of different heavy timber structure systems with different heights under wind loads.

木材作为一种可再生材料，有潜力成为低层和高层建筑的建筑材料。与其他建筑材料相比，木材在此类建筑的建造中的市场份额是最低的。有几种重型木结构系统，例如交叉层压木材（CLT）、钉合层压木材（NLT）、胶合木刚性框架、胶合木支撑框架和混合梁。然而，尚未进行详细的研究来评估不同重型木结构系统在风荷载下的性能，也没有准确而简单的分析和设计工具来处理此类建筑的结构设计。该研究计划的最终目标是开发可用于分析和设计不同重型木结构系统的综合指南和工具。目前的研究是通过评估不同高度的不同重型木结构系统在风荷载下的行为来实现最终目标的第一步。
