: Within the STRAP Concrete Post-Processor , classify your specific load cases for long-term deflection calculation. The module calculates reinforcement layouts and references them to find the true cracked moment of inertia ( Icrcap I sub c r end-sub
ATIR Engineering Software is currently modernizing its entire codebase. Version updates for 2024 and beyond have introduced features crucial for handling thermal and cracked environments. The latest versions of ATIR STRAP and BEAMD offer enhancements in multi-storey stage construction and advanced calculation methods for creep and shrinkage—factors that are exacerbated in "hot" cracked beams. atir strap and beamd with crack hot
Acts as the primary horizontal load-bearing member, typically constructed from high-strength structural steel or reinforced refractory concrete.
Do not design concrete elements using their gross, uncracked stiffness properties. To fix hot spots, reduce the stiffness of your elements to mimic real-world cracked behavior according to building codes (e.g., ACI 318): Reduce Iycap I sub y Izcap I sub z to 0.35 or 0.50 . Beams (Torsion): Reduce the torsional constant What was the (e
Supports the design of composite steel and concrete beams and columns.

Understanding how ATIR STRAP handles the interaction between beams and finite element shells is essential for eliminating these artificial stress spikes and producing safe, buildable designs. The Mechanics of Strap and Beam Connections
