THE EFFECT OF EPOXY-COATED REINFORCEMENT AND CONCRETE QUALITY ON CRACKING OF FLAT PLATE SLAB-COLUMN CONNECTIONS

This paper describes the response of concrete specimens that represent typical slab-column connections in parking garage structures. Three slab-column specimens were constructed with normal-strength concrete and three with high-performance concrete. Uncoated reinforcing bars and two different epoxy coating thicknesses were used in the test specimens. Each slab-column specimen was supported on a single column and loaded at the four corners to simulate the moments and shears in the slab. The high-performance concrete specimens exhibited smaller crack widths for both dead and live loads. Specimens reinforced with epoxy-coated bars showed larger crack widths than those reinforced with uncoated bars. An increased coating thickness resulted in larger crack widths. Crack widths predicted were compared to test results.
