Models for Punching Shear Capacity in Concrete Slabs

, 2013
Model Code 2010 was published in the spring of 2012 by the International Federation for Structural Concrete (fib), and presents a whole new model for punching shear design. Whereas the method for punching shear design in Eurocode 2 is mainly empirical, the method in Model Code 2010 is grounded in a physical model called the Critical Shear Crack Theory.

Punching Shear Capacity of Fibre Reinforced Concrete Slabs with Conventional Reinforcement : Computational analysis of punching models

, 2012
Steel fibre reinforced concrete is not a novel concept, it has been around since the mid-1900s, but despite its great success in shotcrete-reinforced rock walls and industrial floors it has not made any impact on either beams or elevated slab. Apparently, the absence of standards is the main reason.

An Assessment to Benchmark the Seismic Performance of a Code-Conforming Reinforced-Concrete Moment-Frame Building [PDF]

, 2008
This report describes a state-of-the-art performance-based earthquake engineering methodology that is used to assess the seismic performance of a four-story reinforced concrete (RC) office building that is generally representative of low-rise office ...

Filling a Gap in Materials Mechanics: Nanoindentation at High Constant Strain Rates up to 105 s−1

Small, EarlyView.
A piezoelectric nanoindentation platform enables constant strain‐rate testing up to 105 s−1, extending experimental capabilities to extreme deformation regimes. Distinct hardness upturns are revealed across crystalline and amorphous materials, verified as intrinsic responses through quasi‐static reloading.

Optimizing UHPC Layers to Improve Punching Shear Performance in Concrete Slabs

Buildings
Flat slabs supported by columns without beams are widely used in construction owing to their economy and efficiency. However, brittle punching shear failure at slab–column connections can cause progressive collapse.

Experimental investigation of reinforced concrete members subjected to reversed cyclic axial loading

Structural Concrete, EarlyView.
Abstract This paper presents an experimental campaign of five reinforced concrete members subjected to cyclic axial loading alternating between tension and compression. Fiber optical sensors and digital image correlation, in combination with automated crack detection and measurement, were used to investigate, among other aspects, the development of ...

Load carrying capacity of skirted foundation on sand [PDF]

, 2013
Skirted foundations are considered to be a viable foundation for a variety of offshore applications. Skirted foundations are used widely offshore, either as a single foundation system for gravity based structures or as discrete foundation units at the ...

Nonlinear analysis of flat post‐tensioned concrete slab–edge column connections

Structural Concrete, EarlyView.
Abstract This study presents nonlinear finite element analyses to investigate the punching shear behavior of unbonded post‐tensioned concrete flat slabs at slab‐edge column connections. A parametric analysis was conducted to evaluate the influence of four critical parameters on the punching shear resistance: the distribution of prestressing tendons ...

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...
