Shear strength of members without transverse reinforcement as function of critical shear crack width

Aurelio Muttoni, Miguel Fernández Ruiz

This paper investigates the shear strength of beams and one-way slabs without stirrups based on the opening of a critical shear crack. The shear-carrying mechanisms after the development of this crack are investigated. On this basis, a rational model is de ...

New Connection System for Confined Concrete Columns and Beams. I: Experimental Study

Yu Bai

A new connection system for a concrete filled steel tube composite column and reinforced concrete beams is proposed. In this connection, the steel tube is interrupted while the reinforced concrete beams are continuous in the joint zone. Multiple lateral ho ...

Detail design of the MPU Heavy Lifter

Miguel Fernández Ruiz, Hannes Ludescher

This paper gives insight into detail design of the MPU Heavy Lifter. The innovative structure is developed for offshore heavy lifting operations like removing or installing platforms. Its hull is composed of highly reinforced and prestressed lightweight co ...

Quantification of effects of fly ash type on concrete early-age cracking

The mechanisms that contribute to early-age cracking are complex. Determining the relative importance of each mechanism as well as the combined cracking potential for a given concrete material is essential for the concrete industry to construct structures ...

Equivalency points: Predicting concrete compressive strength evolution in three days

Ian Smith, Karen Scrivener, Marco Viviani

Knowledge of the compressive strength evolution of concrete is critical for activities such as stripping formwork, construction scheduling and pre-stressing operations. Although there are several procedures for predicting concrete compressive strength, rel ...

Laboratory tests of composite wood-concrete beams

Julius Natterer

Exploratory research related to the effectiveness of layered composite solid wood-concrete floor systems is described. Rectangular beams comprised of a concrete layer atop a solid dimension lumber layer were load tested. Interlayer force transfer is accomp ...

Punching shear strength of reinforced concrete slabs without transverse reinforcement

Aurelio Muttoni

A mechanical explanation of the phenomenon of punching shear in slabs without transverse reinforcement is presented on the basis of the opening of a critical shear crack. It leads to the formulation of a new failure criterion for punching shear based on th ...

Simplified concrete resistivity and rapid chloride permeability test method

A simplified method of measuring concrete resistivity, as an index of permeability, has been developed that is similar to ASTM C1202 or the rapid chloride permeability test (RCPT). It is significantly faster and easier to perform, however In this test, cyl ...

Macroscopic dynamics of complex metastable systems: Theory, algorithms, and application to B-DNA

John Maddocks

This article is a survey of the present state of the transfer operator approach to the effective dynamics of metastable complex systems, and the variety of algorithms associated with it. We introduce new methods, and we emphasize both the conceptional foun ...

Inelastic wide-column models for U-shaped reinforced concrete walls

Katrin Beyer, Alessandro Dazio

Although core structures are often used in reinforced concrete buildings as members providing lateral strength and stiffness, experimental and numerical studies on their inelastic behavior are scarce. In an experimental program recently completed at the ET ...
