This study investigated the vertical compressive and horizontal shear capacities of traditional Chinese brick masonry arches constructed using different bricklaying patterns. Rowlock-stretcher arch specimens, employing both one-rowlock-one-stretcher and two-rowlock-two-stretcher patterns, were fabricated using traditional blue bricks and lime mortar and subjected to vertical concentrated loads and low-cycle horizontal loading. The resulting failure modes, load-bearing capacities, and displacement responses were analyzed. Under vertical loading, the rowlock-stretcher arches predominantly exhibited a four-hinge failure mechanism, characterized by a plastic hinge at the crown and diagonal cracks extending from the quarter-span point on the loaded side to the load point. The two-rowlock-two-stretcher configuration demonstrated delayed crack propagation and enhanced load capacity. Under low-cycle horizontal loading, cracks in the rowlock-stretcher arches propagated upward from the quarter-span point on the loaded side; conversely, the two-rowlock-two-stretcher configuration displayed reduced ductility but increased load capacity. Significantly, after the collapse of the outermost rowlock course, the inner rowlock-stretcher structure retained substantial residual load-bearing capacity. These findings advance our understanding of the structural behavior of traditional Chinese brick masonry arches and inform the development of scientifically sound preservation strategies.

摘要

This study investigated the vertical compressive and horizontal shear capacities of traditional Chinese brick masonry arches constructed using different bricklaying patterns. Rowlock-stretcher arch specimens, employing both one-rowlock-one-stretcher and two-rowlock-two-stretcher patterns, were fabricated using traditional blue bricks and lime mortar and subjected to vertical concentrated loads and low-cycle horizontal loading. The resulting failure modes, load-bearing capacities, and displacement responses were analyzed. Under vertical loading, the rowlock-stretcher arches predominantly exhibited a four-hinge failure mechanism, characterized by a plastic hinge at the crown and diagonal cracks extending from the quarter-span point on the loaded side to the load point. The two-rowlock-two-stretcher configuration demonstrated delayed crack propagation and enhanced load capacity. Under low-cycle horizontal loading, cracks in the rowlock-stretcher arches propagated upward from the quarter-span point on the loaded side; conversely, the two-rowlock-two-stretcher configuration displayed reduced ductility but increased load capacity. Significantly, after the collapse of the outermost rowlock course, the inner rowlock-stretcher structure retained substantial residual load-bearing capacity. These findings advance our understanding of the structural behavior of traditional Chinese brick masonry arches and inform the development of scientifically sound preservation strategies.
