Seismic Damage Assessment of Reinforced Concrete Structure using Non-linear Static Analyses

In this paper, stiffness based damage index (DIc) is introduced and expressed as a simple formula based on nonlinear response got from nonlinear static procedures. It is useful because only once the pushover has to be performed for the inertia loads obtained from equivalent static method given in BIS 1893, to show the degree of damage of structure in question. It is employed to the damage assessment of example RC frames representing different structures. To extend DIc for different performance levels defined in FEMA 356, the damage values are related to drift based damage index. Results show that DIc agrees with drift damage values and is valuable tool for practical applications.

In this paper, bending analysis of exponentially varying functionally graded (FG) plate is presented using trigonometric shear deformation theory (TSDT) considering both transverse shear and normal deformation effects. The in-plane displacement field consists of sinusoidal functions in thickness direction to include transverse shear strains and transverse displacement include the effect of transverse normal strain using the cosine function in thickness coordinate. The governing equations and boundary conditions of the theory are derived using the virtual work principle. System of governing equations, for simply supported conditions, Navier's solution technique is used to obtain results. Plate material properties vary across thickness direction according to exponential distribution law. In the current theory, transverse shear stresses are distributed accurately through the plate thickness, hence obviates the need for a shear correction factor. TSDT results are compared with those from other theories to ensure the accuracy and effectiveness of the present theory. The current theory is in excellent agreement with the semi-analytical theory.
