Lateral force resisting mechanisms in slab-column connections: An analytical approach

Aurelio Muttoni, Katrin Beyer, Ioannis Sokratis Drakatos

In many countries reinforced concrete (RC) flat slabs supported on columns is one of the most commonly used structural systems for office and industrial buildings. To increase the lateral stiffness and strength of the structure, RC walls are typically adde ...

Use of indentation tests to study the influence of confining stress on rock fragmentation by a TBM cutter

Jian Zhao, Lijun Yin, Hongsu Ma

This paper explores the influence of the confining stress on rock fragmentation under the cutter of tunnel boring machine (TBM) by indentation test. Acoustic emission (AE) system was employed for real-time monitoring the rock fragmentation process during t ...

Punching strength of actual two-way slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Jürgen Einpaul

Many building codes rely on empirical formulations with respect to the punching shear design provisions. Such empirical equations are typically calibrated on the basis of laboratory tests performed on simplified geometries (usually isolated specimens) with ...

Influence of punching shear reinforcement on the flexural response of flat slabs

Aurelio Muttoni, Stefan Lips

Physical punching shear models such as the Critical Shear Crack Theory (CSCT), which is the basis of Model Code 2010 (MC 2010), describe generally the punching strength as a function of the slab deformation. Thus, the prediction of an accurate load-deforma ...

Influence de la précontrainte sur la résistance au poinçonnement de dalles en béton armé

Thibault Clément

Flat slabs are commonly used in Switzerland but also in north America and in many European countries. Slab bridges are also a typical solution for crossing of motorways for example. In both cases, supporting a slab by columns is justified by the simplicity ...

Poinçonnement non symétrique des dalles en béton armé

Luca Tassinari

Punching shear of reinforced concrete flat slabs supported on columns is a failure mode in which the slab fractures around the column. This type of failure is sudden and can be catastrophic in nature. Punching shear generally governs the ultimate limit sta ...

Strengthening of flat slabs against punching shear using post-installed shear reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz

A significant number of existing flat slabs currently require strengthening against punching shear for safety reasons (the increase of applied loads and deficiencies during design or construction) or to comply with more stringent code requirements. Availab ...

Poinçonnement symétrique des dalles en béton armé

Stefano Guandalini

Punching of reinforced concrete and prestressed slabs is usually a critical failure mode for the design and verification of structures such as flat slabs or bridge slabs. Although codes of practice propose several rules for common cases (usually with an em ...

The statistical upper mantle assemblage

Anders Meibom

A fundamental challenge in modern mantle geochemistry is to link geochemical data with geological and geophysical observations. Most of the early geochemical models involved a layered mantle and the concept of geochemical reservoirs. Indeed, the two layer ...

Pressure-Induced Structural Modifications In Mg2Geo4-Olivine - A Raman-Spectroscopic Study

Philippe Gillet

Raman spectra of Mg2GeO4-olivine were obtained from ambient pressure up to 34 GPa at ambient temperature. Under quasi-hydrostatic pressure conditions, the following modifications in the Raman spectra occur as pressure increases: 1) near 11 GPa, two sharp e ...
