Development of slab-to-wall connections assisted by experiments and numerical simulations

Popis výsledku v původním jazyce

Slab to bearing wall connections are used to join precast or cast-in-place concrete floor or roof members to bearing walls. They transfer a vertical load from the horizontal system and, sometimes, diaphragm action by providing moment and shear resistance. The tested connection is part of a novel construction technology requiring a fast and safe fabrication of buildings. In contrast to traditional solutions, where moments in frame corners are transferred by appropriate detailing of bar reinforcement, tensile forces are resisted by inserts anchored in concrete. Structural functionality of inserts was verified by the experimental investigation of a slab-to-wall joint subjected to moment loading. A full-scale specimen was tested whereas the force, deformation and strain responses were monitored. The experiment was simulated numerically by program ATENA. It helped to analyze in detail the structural behavior observed experimentally and explain the resistance model exploiting inserts. The experimental and numerical results were analyzed with emphasis on the anchoring capacity of inserts. The project demonstrates the efficiency of development process based on combining laboratory testing with numerical simulation.
