- Description
- This paper presents the results of an experimental testing program of Unreinforced Masonry (URM) walls with openings subjected to cyclic in-plane shear loading. The primary aim of the experimental program is to obtain force-displacement relationships for URM walls with openings to be used in future nonlinear static pushover analyses of entire URM buildings. The experimental program consists of testing of 12 full-scale wall specimens (3 geometry types × 2 vertical precompression levels × 2 repeats of each test = 12 tests total). The three wall geometries considered are: W1: 3600 mm long × 2400 mm high with an opening of 1200 mm long × 1800 mm high with the bottom of the opening located at the base of the wall ; W2: 3600 mm long × 2400 mm high with an opening of 1200 mm long × 1200 mm high with the bottom of the opening located at the base of the wall ; W3: 2600 mm long × 2400 mm high with an opening of 1000 mm long × 1000 mm high with the bottom of the opening located 700 mm up from the base of the wall. All wall specimens tested are representative of recent Australian construction practice and consist of single leaf thickness (110 mm thick) clay brick masonry units of dimensions 230 mm × 110 mm × 76 mm with a cementitious mortar of mix proportions (by volume) 1 cement: 1 lime: 6 sand. Steel lintels are used to support the masonry spandrel elements above the wall openings. The walls tested exhibited a combination of pier and spandrel flexural and shear failure modes, with ultimate displacements in the range of 8-28 mm (0.3%-1.2% drift) observed. Structural ductility factors in the range of 4.0-25.6 were calculated for the walls tested.
