Analytical Investigation of the Effect of Brick Partition Wall on Building Frame

Structural analysis of building frames represents an important field of application of digital computers to use stiffness approach in order to evaluate their complete stress and deflection behavior. Generally a frame is analyzed without the presence of brick wall in the frame. In the present study, if the brick walls present in the frame whatever the variation of reaction, bending moment, shear force, displacement or deflection of the frame which is then compared to the frame without the brick wall. In the present investigation a five storied building frame has been analyzed under various load combinations. From the frame analysis, it has been investigated that if no nodes of brick wall are coincide with the nodes of beam and column then whatever its effect on moment, reaction, shear force, displacement or deflection. This type of building frames are highly undesirable in lateral loads and also in seismically active areas because in this case there are no connection between the brick wall and the beams and columns, and due to this reason the building frames which have consistently performed very poor behavior and cracks may occur under the beams and also at the side of partition wall. In another case, if a brick wall node is coincided with beam and column nodes then its effects on the results are measured. The whole work has been performed by using computer software STAAD-PRO from which different parameters are computed. If there are well connections between beams and brick nodes, it increases the stiffness of the structure. This reveals significance of frame analysis which provides an accurate and economical solution. A good agreement between the values of various force functions given by approaches is exhibited. It is found that regular system of bays and same length and thickness of connecting beam is favorable for reducing deflection in partition wall. If there are proper connections among the brick walls and the beams and also with the columns than the deflection will be decreased and Stiffness will be increased.
