摘要：

In order to analyze the fire behavior of the two-way concrete slab with out-of-plane restraints on corners under constant loads, one fire test which includes the wireless temperature measurement and infrared detection was conducted to obtain the temperature field along the depth, the reinforcement temperature, the out-of-plane and in-plane deflection, crack and the corners' out-of-plane restraint reaction. The test results also were compared with the relevant tests at home and abroad. Results indicate that the wireless measurement could get high-accuracy results with easy use, and the infrared detection technology can have a real-time observation on the slabs' cracks. The cracking pattern and deflection of the slab with out-of-plane restraints on the corners is clearly different from those of the simply support slabs, and arc-shaped cracks easily occurred near to slabs' corners. The corners' restraint degree has a considerable effect on the arc-shaped crack distribution and development of the slabs' corners. © 2017, Editorial Office of Journal of Building Structures.
