Three aspects of one-third wall model tests were conducted to demonstrate the stress distribution of studs of light-frame wall under vertical distributed and lateral loads. Analyses with finite element method also conducted to verify the accuracy of numerical simulations employing six analytical modeles. The experimental and analytical results indicate, i) Various analysis models including the model with pin joints predicte in high accuracy the stress distribution of studs under vertical distributed load, ii) Rigidity evaluation of the joint between plywood and stud is important for predicting the lateral displacement of bearing-walls, iii) Various analysis models predict in remarkable accuracy the position and magnitude of the maximum and the minimum stress generated in the wall under lateral load, iv) The analysis model evaluated appropriately the support conditions of the lower part of the bearing-wall predict the stress of studs, bending moments of wall and the inflection point of frame with sufficient accuracy.
