Online Implementation Of Structural Analysis Tool For Remote Learning, Ghada El-Mahdy, Amany Micheal
Civil Engineering
The delivery of a structural analysis module to architectural or civil engineering students needs the visualization of certain diagrams, such as the internal force diagrams and the elastic line. These diagrams are difficult to grasp for students new to structural analysis and need a lot of practice to become proficient in drawing them. Current structural analysis textbooks with electronic platforms do not include tools to draw the internal force diagrams or deflection. This has led to the initiative of creating an online structural analysis tool to enable the student to easily apply different loadings on different statical systems to draw …
Deep Learning Techniques For Structural Response Prediction During Strong Ground Motions, Ahmed A. Torky, Susumu Ohno Prof., Toshide Kashima Prof.
Deep Learning Techniques For Structural Response Prediction During Strong Ground Motions, Ahmed A. Torky, Susumu Ohno Prof., Toshide Kashima Prof.
Civil Engineering
In this paper, deep learning techniques are applied to predict a building’s structural response to strong ground motions. Data from sensors near and inside structures measure accelerations during strong ground motions. The Building Research Institute (BRI) ANX building, an eight-story structure, has experienced major earthquakes since 1998. Sensors in the building provide and accumulate big data of historic events. Changes of the natural frequency of the ANX building from the big data is initially quantified. The time-series data of the historic events can be used to predict future response to future events using deep learning models rapidly. Although previous literature …
Experimental Investigation For Moment Redistribution In Continuous Rc Beams Top Strengthened With Cfrp And Steel Plates, Amr Ibrahim, Shady Salem, Ayman Khalil, Mahmoud El-Kateb
Experimental Investigation For Moment Redistribution In Continuous Rc Beams Top Strengthened With Cfrp And Steel Plates, Amr Ibrahim, Shady Salem, Ayman Khalil, Mahmoud El-Kateb
Civil Engineering
An experimental study was conducted on eight T-section continuous reinforced concrete beams top strengthened with CFRP and steel plates. The beams had a constant cross section and flexural steel reinforcement which was designed to prevent brittle failure due to crushing of concrete before steel yielding. The plates were installed on both sides of the slab above the beam web as near surface mounted or externally bonded to investigate the effect of different plating techniques on the moment redistribution in reinforced concrete beams. The number of plates in each specimen was changed. Steel stirrups were used and designed so that no …
Moment Redistribution In Continuous Rc Beams Top Strengthened With Steel And Cfrp Plates, Amr Ibrahim, Ayman Khalil, Shady Salem, Mahmoud El-Kateb
Moment Redistribution In Continuous Rc Beams Top Strengthened With Steel And Cfrp Plates, Amr Ibrahim, Ayman Khalil, Shady Salem, Mahmoud El-Kateb
Civil Engineering
It is common practice to retrofit continuous reinforced concrete (RC) beams by fiber reinforced polymer (FRP) or steel plates. This can cause a significant amount of moment redistribution (MR) which results in an efficient and economic design when taken into consideration. There is lack in research regarding MR in continuous RC beams when strengthening plates are applied only at the top side at the hogging regions. The main purpose of this paper is to assess MR in continuous RC beams top strengthened with steel and/or carbon fiber reinforced polymer (CFRP) plates. In this respect, a nonlinear finite element model was …
Assessment Of Smc Frames Under Different Column Removal Scenarios, Mariam Ehab, Mina Malak
Assessment Of Smc Frames Under Different Column Removal Scenarios, Mariam Ehab, Mina Malak
Civil Engineering
Throughout the past decades, failure of structures threatening the lives of humans had been popular whether through structure failure due to human error such as Hyatt Regency walkway collapse, 1981, terrorist attacks on the American embassy attack in Nairobi, Kenya 1998 and the famous 9/11 attacks in 2001 and many more. As a result of these incidents, The Unified Facilities Criteria (UFC) was developed concerning the progressive collapse issues by analyzing different types of structures under column loss and studying the overall structural behavior. However, the (UFC) didn’t scope on the local behavior of the structural components and its connection …
Progressive Collapse Assessment Of Post-Tensioned Reinforced Concrete Flat Slab Structures Using Aem, Amgad Mahrous, Mariam Ehab, Hamed Hadhoud
Progressive Collapse Assessment Of Post-Tensioned Reinforced Concrete Flat Slab Structures Using Aem, Amgad Mahrous, Mariam Ehab, Hamed Hadhoud
Civil Engineering
Progressive collapse is defined as the failure of a primary vertical element of a structure, which may result in the failure of adjoining elements, consequently, leads to a partial or total collapse of the structure. Unified Facilities Criteria (UFC) and General Services Administration (GSA) guidelines used to assess the behavior of structures subjected to progressive collapse as a result of the loss of primary vertical support. For the current case study, numerical analysis is carried out for a typical ten-story reinforced concrete post-tensioned flat slab structure subjected to primary vertical element loss (corner column, edge column, internal column, edge shear …
