The Earthquake Engineering Online ArchiveNonlinear Analysis of Reinforced Concrete Panels, Slabs and Shells for Time Dependent EffectsKabir, Ahmad F. UCB/SESM-1976/06, Dept. of Civil Engineering, University of California, Berkeley, 1976-12, 248 pages (500/C23/76/06) A numerical method of analysis is developed to trace the quasi-static responses of various types of reinforced concrete structures under sustained loads. Ultimate collapse of shear panels, slabs of arbitrary geometry and free-form, shell-type structures are then predicted considering local failures in steel and concrete along with deterioration of structural stiffness due to progressive cracking. A finite element tangent stiffness formulation coupled with a time step integration scheme is developed to analyze the reinforced concrete systems. Numerical results demonstrate close correspondence with available experiemental data. Available online: http://nisee.berkeley.edu/documents/SEMM/SEMM-76-06.pdf (13 MB) |
