When software analysis indicates excessive crack widths due to thermal combinations, engineers must optimize reinforcement detailing within the ATIR Concrete Post-Processor .
Whether it’s a spreader beam used for lifting or an I-beam in a building’s frame, "cracks" and "heat" are the two primary enemies of steel.
Because 1D elements have 6 degrees of freedom at a single node and 2D shell elements model in-plane and out-of-plane stiffness, the boundary where they intersect undergoes massive forces. If the connection is modeled rigidly without accounting for real-world material cracking and flexibility, ATIR STRAP will output extreme peak stresses—the "hot spots." What Causes "Crack Hot" Stress Spikes in ATIR STRAP?
