Real Records Scaling Factors Optimization To Fit The Syrian Design Spectra Using Genetic Algorithm, Seraj Jdyd

Journal of the Arab American University مجلة الجامعة العربية الامريكية للبحوث

After selecting real seismic records it is necessary to scale these records to match the intensity of the earthquake expected for the site. Generally, scaling can be made by ground motions uniform scaling in time domain which is simply scaled up or down the ground motions uniformly to best match (in average) the target spectrum within a period range of interest. It’s an engineer’s job to find the best scaling factors to best match the target spectrum, which is a complex task, so we employed the Genetic Algorithm (GA) in finding those scaling factors to achieve the best results.

A Framework For Augmenting Building Performance Models Using Machine Learning And Immersive Virtual Environment, Chanachok Chokwitthaya

LSU Doctoral Dissertations

Building performance models (BPMs), such as building energy simulation models, have been widely used in building design. Existing BPMs are mainly derived using data from existing buildings. They may not be able to effectively address human-building interactions and lack the capability to address specific contextual factors in buildings under design. The lack of such capability often contributes to the existence of building performance discrepancies, i.e., differences between predicted performance during design and the actual performance.

To improve the prediction accuracy of existing BPMs, a computational framework is developed in this dissertation. It combines an existing BPM with context-aware design-specific …

Flexural Behaviour Of Over-Reinforced Concrete Beam Using External Steel Plate, Shatha Sahib Kareem

Student Works (2020-2029)

Over-reinforced concrete beam fails by crushing of the concrete compression zone before the yielding of steel reinforcement in the tension zone. An over-reinforced concrete beam may failed suddenly without warning before failure as the failure is instantaneous. Therefore, numerous codes of practices recommended a beam design to avoid brittle failure. However, in some situations, due to the limitation of spaces, using over-reinforced concrete beam is not avoidable. Previous researches showed that it is possible to design an over-reinforced concrete beam without brittle failure using the methods such as helical-reinforcement, short-stirrups, and hybrid-system. This study is an effort to investigate the …
