RESEARCH ON ESTIMATION FOR LOAD-DEFORMATION CURVES OF MUD-WALLS WITH OPENINGS UNDER CONSIDERATION OF BENDING OF COLUMNS

–Results of lateral loading tests and its estimation for mud-walls placed on foundation–

Abstract

To examine the load-deformation relationships and failure modes of the mud-walls placed on foundation, static tests under lateral cyclic loads were carried out. The estimation method of load-deformation curve for the mud-walls with openings was proposed. It is considering the bending of the columns and pullout of the lintel. The estimation results were compared with the experimental results of the specimens that are composed of hanging mud-walls, window back mud-walls and narrow side mud-walls. The estimation results were similar to the corresponding experimental results; therefore, the usability of the estimation method was confirmed under the conditions set in this paper.
