Abstract The bond between prestressing strands and concrete within the dead-end zone of a post-tensioned concrete member significantly influences the effectiveness of the strand-concrete system. However, the existing code equations for determining de

Punching capacity is one of the main items in the design of both pre-stressed and non-pre-stressed flat slabs. All international design codes include provisions to prevent this type of failure. Unfortunately, there is no code provision for UHPC yet,
One of the structural systems that are widely used nowadays is post tensioning concrete slabs with special shaped dead end (H-anchorage dead end). The special shaped dead end is formed by using a certain hydraulic jack that enables the shaping of an

Dead and live load demands can substantially increase when the span lengths of existing bridges are lengthened to accommodate widening projects for underlying roads or highways. Thus,the existing bridge superstructures are required to be strengthened

Structural lightweight concrete (LWC) is of high importance to the construction industry, as it is cost effective and highly advantageous. A new kind of LWC was produced at the Department of Structural Engineering of Ain Shams University in 2005, whi

Abstract The aim of this research is to present correction factors for the punching shear formulas of ACI-318 and EC2 design codes to adopt the punching capacity of post tensioned ultra-high-performance concrete (PT-UHPC) flat slabs. To achieve that
