讲座内容：

正交胶合木(CLT)是一种新型的建筑结构材料，由三层或三层以上的方向交替的木材层组成，近年来在欧美发达国家的建筑业中得到越来越广泛的重视。CLT作为一种工厂预制的工程木产品，其强度和刚度相对较大，易于满足结构在各种加载条件下的可靠性要求。在本次讲座中，将对CLT结构的设计和施工相关理论、性能、实际应用、局限性和解决方案等进行回顾与探讨。

Cross-laminated Timber (CLT) is a relatively new building material that has gained recent attention in the world construction industry. CLT is a prefabricated, engineered wood product, composed of three or more plies of lumber with alternating ply directions. CLT is relatively strong and stiff, with the potential to meet the requirements for structures that are subjected to a variety of loading conditions. In this report, the theory, performance, practical applications, limitations and solutions pertaining to design and construction methods of CLT will be retrospected.
