Probabilistic assessment of the lateral behaviors of column-and-tie wooden frame (CTWF) with uncertainty in the gaps inside the wood-wood connections is significant for preventive protection of wooden structures. This typical kind of traditional wooden structure has connections such as the semi mortise-tenon (SMT) connections, penetrated mortise-tenon (PMT) connections, lintel-mortise (LM) connections and column foot (CF) connections. The modelling of these connections is introduced and beam element model of the whole CTWF considering different gaps inside the connections is described. Finally, the probabilistic lateral behavior of the CTWF is assessed with a Weibull distribution for the gaps fitted from the field measured data. The effect of different combinations of gaps inside the wood-wood connections on the CTWF is studied. Results obtained demonstrate the lateral performances of the frame and they may serve as reference for the retrofitting and reinforcement of typical CTWFs.

有连接间隙的柱系木框架侧向行为概率研究

在木-木连接内部间隙存在不确定性的情况下,对柱系木框架 (CTWF) 的横向行为进行概率评估,对于木结构的预防性保护具有重要意义。这种典型的传统木结构有半榫(SMT)连接、穿插榫(PMT)连接、楣榫(LM)连接和柱脚(CF)连接等连接方式。介绍了这些连接的建模,并描述了考虑连接内部不同间隙的整个CTWF的梁单元模型。最后,CTWF 的概率横向行为通过 Weibull 分布来评估,该分布是根据现场测量数据拟合的间隙。研究了木-木连接内部间隙的不同组合对 CTWF 的影响。
