للكاتب Sameh. El-Refaie Civil Engineering Department, Faculty of Engineering at El-Mataria, Helwan University, Cairo, Egypt Abstract Standard codes of practice give minimum and maximum limits for concrete and steel reinforcement dimensions in order to satisfy serviceability and ultimate limits. However, there exist optimum dimensions for concrete and steel reinforcement that not only satisfy the code provisions but also they give …

للكاتبين A.Kadid , R..Chebili,A.Zine ABSTRACT: The Boumerdes 2003 earthquake which has devastated a large part of the north of Algeria has raised questions about the adequacy of framed structures to resist strong motions, since many buildings suffered great damage or collapsed. To investigate the behaviour of framed buildings under future expected earthquakes, a non linear static pushover analysis has been …

للكاتب Nayer A. EL-Esnawy Structural Engineering Department, Faculty of Engineering, Cairo University, Giza, Egypt ABSTRACT An adaptive pushover procedure incorporating a weighted vector combination strategy of the modal lateral forces for multistory frame buildings is presented. In the proposed pushover procedure, the lateral force distribution prescribed along the height of the frame building is continuously updated by combining the instantaneous …
