Figure 6: Expansion joint seal working in both shear and tension with failures at shear areas and transitions. Problem #3: Improper building expansion joint configuration Not to be overlooked, expansion joint configuration is equally important to accommodating building movements. Expansion joint seals are typically designed to work in tension across the joint width. As shown […]

Figure 3: Panel-to-panel connection repairs. Problem #1: Inappropriately constrained building materials and a lack of consideration for internal forces and stresses induced by volume change When a structural engineer inappropriately constrains concrete structural members, preventing building movements associated with volume change, connection distress is an inevitable result. At a parking garage in a northern climate, […]
