For specialized applications such as beam openings, post‑tensioned beams, or beams with unusual cross‑sections, STRAP’s finite element engine can perform more advanced cracked section analyses. Unlike traditional frame analysis, which assumes fully uncracked or fully cracked stiffness, modern practice often employs a bi‑linear or tri‑linear moment‑curvature approach. STRAP’s design postprocessors for concrete structures allow engineers to check member capacity and generate design reports that account for cracked section properties.
International design standards including ACI 318, Eurocode 2, BS 8110, and IS 456 impose strict crack width limits for serviceability limit states (SLS). These limits typically range from 0.3 mm to 0.4 mm for normal exposure conditions, with narrower limits for aggressive environments. Exceeding these limits can compromise durability by allowing moisture and chlorides to penetrate and corrode embedded reinforcement, and lead to unacceptable serviceability performance such as excessive deflection or vibration. Cracks also impair aesthetic quality and can negatively affect user perception of structural safety.
The program supports three-dimensional modeling of nodes and elements including beams, columns, walls, and foundations for steel, concrete, or composite structures with complex geometries. Engineers can perform both static and dynamic analyses—linear static analysis, dynamic analysis, wind load analysis, seismic (earthquake) analysis, and moving load analysis—with automatic wind and earthquake load generation based on international code provisions.

: Serves as the dedicated, component-oriented module integrated within STRAP to specifically detail, check, and produce schedule layouts for concrete beams. Phase 1: Analyzing Beam Cracking in ATIR STRAP
BEAMD is the complete and totally integrated solution for reinforced concrete beam design, detailing, drafting, and scheduling. It transforms what is traditionally a tedious, error‑prone manual process into a fast, efficient, and interactive design experience. BEAMD can be used independently, integrated with STRAP, or connected to a CAD system, giving engineers exceptional flexibility.
If the wood beam is cracked but the ATIR strap remains intact:
A cracked strap or beam in a structural assembly can compromise load transfer and safety. This article explains how to identify cracks, assess severity, select repair methods, perform repairs, and prevent recurrence. It applies to common materials (steel, timber, and reinforced concrete) and typical strap/beam connections (bolted, welded, nailed, or adhesive).
