The thermal loading generated an upward deflection at the mid-span of 0.425 to 0.570 inch (10.8 to 14.5mm). The behavior of the beams used in the tests was generally the same. Visual inspection conducted during the thermal loading detected only minor, non-structural cracking in the partial-depth conventionally grouted connection.

Effect of diagonal cracks on shear stiffness of pre

During service period, due to the overload or other non-load factors, diagonal cracks of the pre-stressed concrete beam are seriously affecting the safety of the bridge structure. The purpose of this paper is to quickly realize the shear bearing capacity and shear stiffness through maximum width of the diagonal cracks and make correct judgments.

The deck moves, putting pressure against the pool wall. As a consequence, the pool's bond beam may crack. If waterline tile is affixed to the problem area, the tile will fracture as well. Similar cracking can result from a common technique used to prepare for the coping. Workers level the top of the bond beam by applying a layer of mortar.
