Behaviour of Smart Steel Column‐Beam Connection Under Blast Loading

The generated damages in steel structures due to terrorist attack explosion has attracted structural engineering communities, because the effect of blast loading is extremely sever and destructive. behavior Superelastic Nickle Titanium Shape Memory Alloy (NiTi SMA) beam-column connection was infrequently studied under loading. present study develops smart performance proposed configuration evaluated numerically make better understanding conceptual design NiTi SMA-based bolted connections. stiffness strength determined based on Eurocode joint procedures. Analytically, Simplified Kingery Airblast Calculations approach used generate time history reflected overpressure parameters. austenite NiTi-SMA introduced global 2D frame model by moment rotation capacity curves. components are verified Ultimate Limit State (ULS) using results model. outputs from sub-numerical models. sub-models examined finite element software code. result shows that hysteresis flag-shaped loop well expressed sub-models' numerical solutions. As a result, can highlight efficiency terms energy dissipation successfully.
