Assuming a link-slab of 5% the length of each adjacent deck slab as suggested by Caner and Zia
[4],the imposed tensile strain related to imposed deformation by temperature,live load and
shrinkage is calculated to be around 1.6%,adopting a factor of safety of two [5].This implies
that cracking in concrete link-slabs is inevitable since normal concrete has a tensile strain capacity
of 0.01%.Furthermore,cyclic fatigue loading due to traffic movements may be expected to widen
the width of concrete cracks over time [6].
Assuming a link-slab of 5% the length of each adjacent deck
假设如Caner 和 Zia[4]建议的那样,链接桥板为每一相邻桥板长度的5%,那么与因为温度、活荷载及搜索引起的变形相关的施加的拉伸应变,经计算大约为1.6%(采用安全系数2[5]).这意味着,混凝土链接桥板的裂纹是不可避免的,因为通常的混凝土只有0.01%的拉伸应变能力.此外,由于交通流动情况引起的循环疲劳荷载预计可能随着时间的推移会扩大混凝土裂缝的宽度[6].
