A major part of central European infrastructure buildings was designed decades ago and has different needs strengthening. Increasing traffic volume, increasing axle loads, a growth in transport volume as well more restrictive design rules are the reasons why support regions existing bridges flat slabs often show lack punching resistance today. At University Innsbruck, system for subsequent stre...

Punching shear-reinforced flat slabs can fail in three modes: (1) inside the zone, (2) outside or (3) at maximum punching shear capacity. By using theory of structural systems reliability, this study investigates how these failure modes combined affect safety level reinforced concrete with reinforcement, and ultimately, variation partial factors. Based on DIN EN 1992-1-1 together German Nationa...

Punching capacity is one of the main items in design both pre-stressed and non-pre-stressed flat slabs. All international codes include provisions to prevent this type failure. Unfortunately, there no code provision for UHPC yet, hence, aim research experimentally investigate impact column dimensions punching reinforcement on post-tensioned slabs compare results with codes’ evaluate its validit...
