Structural solution of the horizontal joint of floor slabs in girderless frame

Despite the widespread use of monolithic construction, precast concrete remains in demand construction residential and administrative buildings. Regardless advantages technology quality work, it is necessary appropriate to modernize existing design solutions, which allows you simplify speed up technological operations during construction. Moreover, complex nodes joints, qualification workers important, so simplifying work without losing ensuring strength, stability durability an important task. This problem can be solved by using modern embedded parts joints that do not require welding other operations. In this paper, a constructive solution horizontal joint floor slabs located zone action minimal forces proposed on example girderless frame. The purpose study determine stress-strain state structural loopshaped «PFEIFER» develop recommendations for determining shear compliance. Based analysis results numerical modeling, features operation are revealed. obtained used buildings with precast-monolithic ringless frames, modernization standard solutions as well load-bearing systems made concrete.
