Bond Strength Behaviour of Headed bar with Varying Embedment Length: Headed Bars a new reinforcement pattern - Softcover

Inhaltsangabe

Bond stress increases with increment in embedment length. Pull out load increases with increment in embedment length. The reinforcement can be placed exactly at the desired location. It develops full anchorage strength with very small embedment length, which reduces considerable steel consumption at the junction. It also saves considerable construction costs because the concentrated anchorage can minimize the member size, for example reduce concrete depth, formwork and excavating for footings. Reduced congestion and ease of placing of headed bars will improve construction thus speeding up a project. The concrete also benefits because adequate and vibration will give better concrete consolidation. Anchorage without utilization of bond improves robustness at overload and accidental conditions. If spalling of concrete cover occurs the heads still provide full anchorage without cover.
