    On the Dynamic Response of Funicular Shells and Evaluation of the Behavior Factor

    , M.Sc. Thesis Sharif University of Technology Kadivar, Amin (Author) ; Mofid, Masoud (Supervisor)
    Abstract
    Dynamic behavior of space structures are of great complexities. On the event of severe earthquake these structures exhibit high resistance and on the other hand, their high rigidity and small deformation makes it necessary to pay attention to their dynamic behavior, especially when combined with other types of structural systems. Also due to lack of sufficient codes and references, their dynamic behavior is still unknown to a great extend. Among these kinds of structures, reinforced concrete double curvature shells, and especially funicular shells, are much more important than others. In this thesis, dynamic response of these kind of structures, especially reinforced concrete domes, in... 

    Parametric Study on Seismic Performance of Spherical RC Domes

    , M.Sc. Thesis Sharif University of Technology Gholamrezaie, Amir (Author) ; Vafaei, Abolhassan (Supervisor) ; Mofid, Massoud (Co-Advisor)
    Abstract
    The present parametric study discusses the effective factors on seismic performance of spherical RC domes. For this perpose, a series of domes with different spans, a variety of contact angles (the angle between the bottom of the sphere and the center of the sphere), openings with different areas and various support condition are studied. Then the value of response modification factor and it's components is determined to take into account the effect of each component. The results obtained indicated that the response modification factor increases as the contact angle enhances. However, the span of domes insignificantly affects the value of response modification factor.also analysis on domes...
