Long-Term Deflection Verification in Concrete Bridges
This lecture covers the verification of long-term deflection in concrete bridges according to SIA 260 standards, considering quasi-permanent loads, delayed effects, and temperature. It includes calculations for non-cracked homogeneous sections, deformations due to temperature, and combinations of loads. The lecture also discusses the verification of unfissured sections, moments of cracking, and ultimate limit state verification. The instructor demonstrates the calculation of total moments, verification of non-fissured sections, and the assessment of compression stress. Various software tools are used for the analysis, ensuring compliance with SIA 262 requirements.
