A wall type building is an assemblage of precast wall and slab panels, with various types of joints. Based on the location and orientation, a joint can be a horizontal joint or a vertical joint. To predict the behaviour of a building under lateral seismic forces, it is necessary to characterise the behaviour of the joints. The present research focuses on the in-plane shear behaviour of vertical joints. In the experimental part of the investigation, twelve wall assemblage specimens were tested under direct in-plane shear. Parameters affecting the strength and deformability, such as the type of transverse joint reinforcement (U-bars or loops), amount and spacing of transverse joint reinforcement, and configuration of joint (plane, castellated and castellated with edge lips) were investigated. Based on the observed behaviour, analytical expressions were proposed to predict the shear load versus slip behaviour for each configuration of joint. The proposed expressions can be used to model shear springs (links) between the wall elements, in a computational model of a wall type building. To demonstrate the use of the proposed expressions, a stand-alone jointed wall was modelled using multi-layered membrane elements and shear springs. A few models were developed with different options of modelling the vertical joint. A pushover analysis was performed for each model under the action of lateral loads. The observed behaviour of the experimental specimens, proposed expressions and the results of the numerical analysis are reported in this paper.
