Abstract
This paper presents the p-delta effect and collapse limit state for wooden structures. The static lateral loading tests of walls were conducted to evaluate the p-delta effect and rocking behavior using the wall specifications, width, live load and column-beam connection type, as parameters. Also the load-displacement relationship under a collapse test of a full-sized wooden house was followed using the outcome from shear wall tests. The results of the shear wall tests and following of the load-displacement relationship in a full-sized wooden house are summarized:
1) The bracing and plywood shear wall are close to the column-beam simple frame in the shear performance without making contact with the base beyond 0.1 radium displacement. The collapse limit state cannot be expressed using the shear performance of the frame only. 2) The P-delta effect and rocking behavior are calculated based on the consideration of vertical load, tensile performance of column-beam joints and widths of the walls. 3) The load-displacement relationship and collapse limit state are predicted based on consideration of the contact of panels with the foundation and floor.
