Abstract
The purpose of this study is to propose a prediction method for the collapse mode and its relevant bearing capacity of a timber space frame subjected to vertical load such as excessive snow load. Experimental and analytical studies for the 1/10 scale basic timber structural models were carried out in order to investigate the mode type and its maximum vertical load when some type of collapse mode occured. As a result, the predicted results showed good agreement with the experimental ones when the spring stiffnesses of connections were estimated appropriately through the actual loading test of connection models.
