Lightweight seismic concrete panel with grid-type fiber reinforcement Method for seismic performance of concrete panels
The present invention relates to a lightweight seismic concrete panel with bending strength and energy dissipation capacity improved by using a grid-type fiber reinforcing material made of a composite yarn of carbon fiber and para-aramid fiber. The present invention provides a lightweight seismic concrete panel into which a grid-type fiber reinforcing material is spread and inserted to face a panel surface, wherein the grid-type fiber reinforcing material is woven into leno textile by applying a composite yarn of carbon fiber and para-aramid fiber as weft and warp yarns, respectively. The present invention provides a method for evaluating seismic performance of a concrete panel. The method comprises the steps of: (a) measuring the amount of deflection at the center of a panel for each applied load in accordance with KS F 2566 for the concrete panel; (b) deriving a displacement-load graph that matches the applied load and the amount of deflection at the center of the panel until the concrete panel is destructed in the X-Y coordinate system with the deflection at the center of the panel as the X-axis and the applied load as the Y-axis; and (c) calculating energy dissipation capacity by solving the following [formula 2]. Here, EDC is the energy dissipation capacity, δ_max is the maximum amount of deflection (mm) at the center of the panel, and f(x) is the displacement-load graph.
