Structural Assessment and Repair of Concrete Structures

reinforced concrete can be constructed. As strong as reinforced concrete can be, it also possesses several weaknesses that can contribute to premature failure. If installed incorrectly or without proper maintenance, the useful life of concrete is greatly decreased. Weaknesses can be chemical or physical,

In the design of reinforced concrete slabs the Wood-Armer equations are used extensively. However; their direct application to assessment can result in a conservative estimate of structural capacity. Equations based on the same fundamental principles are derived which provide a more precise measure ofthe ability of a given slab to withstand an imposedfield of moments.
