Abstract: In this paper,the systems of tall building frame-shear wall-thin walled member structures with variable stiffness along the height and complicated plane form and with some floor slab's deformations considered is divided into rigid floor slabs parts and deformed floor slabs parts. The parts of rigid floor slabs are thought of as generalized space thin wall shear-bening colums after treatment of the floor system with coninuum technigue. Deformed floor slabs are thought of as deep beams. Whole structure is thought of as a generalized frame and is then analyzed by matrix displacement method. The method presented in this paper is simpler in claculation and can be used more widely.
