Investigation of a new steel-concrete connection for composite bridges

Jean-Paul Lebet, Dimitrios Papastergiou

A new type of connection for steel-concrete composite bridges was developed by the Steel Structures Laboratory of Ecole Polytechnique Fédérale de Lausanne. Resistance to longitudinal shear is based on the development of shear stresses in the confined inter ...

Structural Response of R-UHPFRC - RC Composite Members Subjected to Combined Bending and Shear

Talayeh Noshiravani

The addition of a thin overlay of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) to Reinforced Concrete (RC) members is an emerging technique to strengthen and protect existing structures and to design durable new structures. Combining UHPFRC wi ...

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 ...

Post-punching behavior of reinforced concrete slabs

Yaser Mirzaei

Reinforced concrete flat slabs are extensively used in buildings and parking garages. Their design is governed by deflection at the serviceability limit state and punching shear at the ultimate limit state. When no punching shear reinforcement is provided, ...

Non-symmetrical punching of flat slabs and slab bridges without transverse reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Juan Sagaseta Albajar

Punching of flat slabs without transverse reinforcement has mostly been investigated in the past for slabs with equal reinforcement ratios in the two directions and loaded under axis-symmetrical conditions. However, in practice, slab bridges as well as man ...

Failure in multiphase geomaterias

Lyesse Laloui

The contributions assembled in the present volume proceed from the lectures of the 2009 ALERT Geomaterials School devoted to the Failure in the multiphase geomaterials. The multiphase behaviour of geomaterials used to be mainly considered from the point of ...

Punching shear strength of R/C bridge cantilever slabs

Aurelio Muttoni, Miguel Fernández Ruiz, Rui Vaz Rodrigues

This paper presents the results of six tests on R/C bridge cantilever slabs without shear reinforcement subjected to concentrated loading. The specimens represent actual deck slabs of box-girder bridges scaled 3/4. They were 10mlong with a clear cantilever ...

Shear strength of reinforced concrete bridge deck slabs

Rui Vaz Rodrigues

Reinforced concrete bridge deck slabs without shear reinforcement can be subjected to concentrated or distributed loads of important magnitude. Under these loads their structural response is not always ductile. In particular under concentrated loads their ...

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 ...

Shear Strength of RC Bridge Deck Cantilevers

Rui Vaz Rodrigues

An experimental and theoretical investigation of the shear strength of reinforced concrete slabs without shear reinforcement is under way at the Ecole Polytechnique Fédérale de Lausanne. The first part of the program consists of 6 tests on two large scale ...
