Punching shear resistance of UHPFRC [PDF]
IABSE Reports, 2019 <p>Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) is a high performance cementitious material with enhanced strength in tension and compression and significantly high energy absorption in the post crack region. Its mix composition is not much dissimilar from that of normal strength concrete.

Influence of the Distribution and Level of Post-Tensioning Force on the Punching Shear of Flat Slabs
Designs, 2022 Punching shear is the most common failure mechanism of slabs that are supported directly on columns. The slab–column connection is always vulnerable to critical punching shear; thus, it is necessary to investigate the effect of various parameters on the ...

Buildings, 2023 Reinforced concrete one-way slabs under concentrated loads can develop different shear failure mechanisms: as wide beams in one-way shear, punching shear around the load or a mixed mode between them. Until now, most publications presented recommendations

Punching Shear Capacity of Continuous Slabs [PDF]
ACI Structural Journal, 2016 Provisions for punching shear design of reinforced concrete slabs are usually calibrated on the basis of results from tests on isolated specimens that simulate the slab zone within the points of contraflexure around a column. However, the punching behavior of interior slab-column connections in actual continuous slabs without transverse reinforcement ...

Comparison of punching shear requirements in BS 8110, EC2 and MC2010 [PDF]
, 2015 This paper compares design provisions for punching shear at internal columns in the superseded British Standard BS 8110, Eurocode 2 (EC2) and fib Model Code 2010 (MC2010).

Punching of reinforced concrete slab without shear reinforcement: standard models and new proposal [PDF]
, 2020 Reinforced concrete (RC) slabs are characterized by reduced construction time, versatility, and easier space partitioning. Their structural behavior is not straightforward and, specifically, punching shear strength is a current research topic.

Derivation of material properties using small punch and shear punch test methods [PDF]
Materials & Design, 2021 The Small Punch (SP) and Shear Punch (ShP) tests are well established mechanical test approaches that have found application in several industrial sectors for material ranking and mechanical property estimation, particularly where more conventional approaches are inhibited.

Slabs strengthened for punching shear with post-installed steel and CFRP connectors
Revista IBRACON de Estruturas e Materiais, 2019 Structural accidents due to punching shear failures have been reported in flat slab buildings. Design recommendations presented by codes can lead to entirely different punching shear resistance estimates for similar situations.

Punching Shear Strength Prediction for Reinforced Concrete Flat Slabs without Shear Reinforcement [PDF]
, 2022 Failure of flat slabs usually occurs by punching shear mode. Current structural codes provide an experience-based design provision for punching shear strength which is often associated with high bias and variance.
