| Abstract | Prolonged static live loads may lead to non-uniform settlement of piles, which may further lead to the development of cracks. A similar case is the cracking of structural beams of an important port in the Samutprakran province of Thailand. The structural beams in the transition area of the port were cracked when the 600 ton crane was stopped for 12 hours due to a hydraulic failure. This kind of static prolonged load was not considered in the structural design. The present study includes forensic investigation, SAP 2000 numerical analysis and finite element modeling, of the affected area, to identify the cause of failure and hence provide a repairing methodology. Simulation of reinforced concrete structure has been done in both the programs with possible load cases and proper support conditions. Settlement of the support has been found to be the main cause of cracks. A comparison of the cracking damage in the field and the numerical results has shown very good agreement. |
