Theoretical Model of Spalling
If the concrete cover is relatively thinner than the spacing,a spalling crack can occur.In general,the angle of spalling becomes smaller with thicker concrete cover.Here,the angle is assumed to be .
In this model,the strain in concrete is [Matsushima 2002],
方程式 (2.3.4.15)
where A is the required displacement for spalling crack at the cracking surface and B is the thickness of concrete cover.Then,considering Hooke's law and the relationship,方程式,the force at the cracking surface,C,is described as follows:
方程式 (2.3.4.16)
Similarly,the stress in corroded reinforcement is,
where E is the force acting on corrosion product,D is the diameter of reinforcement,and
F is the modulus of elasticity of the corrosion products.Since the expansion of reinforcement occurs at both sides of reinforcement,thus the strain in corroded reinforcement is expressed as follows:
where G is the required displacement of reinforcement for a spalling crack and H is the thickness of the corroded reinforcement.Therefore,the force due to steel expansion is,
Considering 方程式,then,the following formula can be obtained,
From the compatibility of displacement,
Finally,I and J can be expressed as follows:
If K exceeds方程式,a spalling crack can develop.
