Chapter 3: Structural Design Of Cross-Laminated Timber Elements

Building using cross-laminated timber (CLT) began in Europe about two decades ago and has used a variety of methods for structural analysis. Experimental testing methods were the most accurate, yet they lacked versatility because changes in lay-up, material, or even manufacturing methods could cause a need for new testing. Consequently, three analytical approaches have been created and are commonly used in Europe as none have been universally accepted to date. The mechanically jointed beam theory, or Gamma Method, appears in Annex B of Eurocode 5 (EN, 2004). According to this theory, the “Effective Stiffness” concept is introduced and a “Connection Efficiency Factor”…
