Ultra high performance fiber reinforced concrete for strengthening and protecting bridge deck slabs

Eugen Brühwiler, Maléna Bastien Masse

An original concept is presented for the durable rehabilitation of concrete bridge deck slabs. The main idea is to add a layer of Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) with or without steel reinforcing bars over the concrete slab to cre ...

Assessing punching shear failure in reinforced concrete flat slabs subjected to localised impact loading

Aurelio Muttoni, Miguel Fernández Ruiz, Juan Sagaseta Albajar

Reinforced concrete flat slab structures are used widely in construction projects due to their economic and functional advantages. Punching shear failure in such structures can have catastrophic effects in the case of, for example, multi-storey framed stru ...

Design for punching of prestressed concrete slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Thibault Clément, António Manuel Pinho Ramos

Prestressing in flat slabs helps in controlling deformations and cracking under service loads and allows reducing the required slab thickness, leading thus to more slender structures and being therefore an economic solution for long spans. However, as a co ...

Experimental and numerical study on structural behavior of a single timber textile module

Yves Weinand, Laurent Humbert, Markus Hudert, Meisam Sistaninia, Masoud Sistaninia

The present work investigates an innovative class of timber structure with potential applications in roofing, facade and bridge construction, called Timberfabric. The development of Timberfabric structures originates from the approach of harnessing the str ...

Instability of Thin-Walled GFRP Webs in Cell-Core Sandwiches under Combined Bending and Shear Loads

Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Behzad Dehghan Manshadi

An analytical investigation of the buckling/wrinkling behavior of GFRP webs in cell-core sandwiches subjected to combined in-plane shear and bending stresses is conducted. Web-core panels are modeled as long orthotropic plates stabilized by a relatively th ...

Crushing and Flexural Strength of Slab-Column Joints

Aurelio Muttoni, Miguel Fernández Ruiz, Roberto Guidotti

In multi-storey buildings, columns are usually not continuous through the slabs to enhance ease of construction. Consequently, in slab–column joints, slabs have to carry column loads in addition to the shear and bending moments due to loads applied to the ...

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 ...

Poinçonnement des planchers-dalles avec colonnes superposées fortement sollicitées

Roberto Guidotti

Flat slabs are commonly used in buildings due to their easiness of construction and economy. In order to keep these advantages, columns are usually not continuous through the slabs in multi-storey buildings. In these cases, the slabs are subjected to large ...

Thin UHPFRC slabs without conventional reinforcement as light-weight structural elements

Aurelio Muttoni, Dario Redaelli, Ana Spasojevic

Ultra-High Performance Fibre-Reinforced Concrete (UHPFRC) is a material characterised by significantly improved mechanical and durability properties compared to other concretes. In recent years, an important research effort has been made to identify approp ...
