Numerical and Experimental Predication of the Structural Cracking Within Reinforced Concrete Structure due to Conventional State of Loading

Abstract

It has been well understanding that the occurrence of various crack patterns in the building during its construction life (from first time of construction up to finishing) then subjected to super imposed load or during the service life. Cracks developed due to exceeding of stresses more than the allowable strength, wherever happened on building component. This research works used the finite element method as a powerful tool to simulate the behavior of full constructed building with both concrete system and brick bearing wall. Where the adopted numerical procedure allows to the users to predict the response of building elements due to conventional state of loading. one of the most important response features was the cracking phenomenon, where the numerical model shown that its capability to predict the cracking sequence from the first time of initiating. The prediction of full response and behavior of each element and their connection, shown that the precise of factor of safety used by the designer, where the analysis prove that the design load was about 67% from the cracking load, and the ultimate load was about 260% from the design load. That will allow more sustainability and stability for long time deformation. Beside the numerical solution, there was an experimental part of study, where site investigation, it shown that all data recorded was constant values and the building was stable. Actually, with no increasing of loading, the building reach its stable state, and defect will not develop. That basically because of good design within conventional state of loading.

Assessing and Mitigating Seismic Risk for a Hospital Structure in Zaruma, Ecuador: A Structural and Regulatory Evaluation

“…Hospitals, functioning round-the-clock and encompassing a diverse range of operations such as emergency rooms and laboratories, stand at the core of the health system, effectively serving as the final point in the rescue chain during disaster response [6,20]. Ensuring the harmonization of seismic behavior across structural and non-structural elements, particularly during serviceability limit states, is critical to guarantee immediate functionality post-disaster [21,22]. Damage assessment and validation under extreme load conditions, such as earthquakes, provide valuable insights into the behavior of structures, thereby highlighting the importance of post-earthquake damage assessment and interpretations or models for comprehending the seismic behavior of buildings [23,24].…”
