New Connection System for Confined Concrete Columns and Beams. II: Theoretical Modeling

Yu Bai

The concept of confined concrete has been widely accepted throughout the structural engineering field, such as the spiral, steel tube, or carbon fiber composite shell confined concrete, etc. In the present study, this concept has not only been used in the ...

Structural implications of ultra-high performance fibre-reinforced concrete in bridge design

Ana Spasojevic

The present research represents a theoretical and experimental contribution to the understanding of the structural behaviour of elements made of ultra-high performance fibre-reinforced concrete (UHPFRC). UHPFRC is investigated as an advanced cementitious m ...

Hybrid FRP-lightweight concrete sandwich system for engineering structures

Erika Schaumann

Hybrid slab systems combining fiber-reinforced polymer (FRP) composites with concrete are promising load-bearing structures, and an increasing number of applications has demonstrated their high potential in terms of structural performance and durability. H ...

Model for predicting the UHPFRC tensile hardening response

Eugen Brühwiler, Emmanuel Denarié, John Wuest

Ultra High Performances Fibre Reinforced Concretes (UHPFRC) are characterised by an ex-tremely low permeability and outstanding mechanical properties. These characteristics make UHPFRC suitable for locally “harden” reinforced concrete structures subjected ...

On Development of Suitable Stress Fields for Structural Concrete

Aurelio Muttoni, Miguel Fernández Ruiz

Strut and tie models and stress fields are methods that can be used for the dimensioning and detailing of reinforced and prestressed concrete structures as well as for the check of existing ones. This paper presents an innovative approach towards the autom ...

Computer-aided development of stress fields for the analysis of structural concrete

Aurelio Muttoni, Olivier Burdet, Miguel Fernández Ruiz

The stress field method is a technique based on the lower-bound theorem of plasticity that can be used for dimensioning, detailing and checking of structural concrete elements. Its use has been traditionally associated with the assumption of simplified (ri ...

Seismic behavior of lightly reinforced concrete squat shear walls

Christian Greifenhagen

This thesis addresses the seismic evaluation of existing buildings. In particular, it focuses on the seismic behavior of lightly reinforced shear walls that are not designed to withstand earthquake actions. A shear strength envelope for the assessment of d ...

Computer-Based Development of Stress Fields

Neven Kostic

Computer-aided approaches for the efficient development of suitable stress fields are useful tools for the structural design of concrete structures. The paper describes a new procedure that is used within a previously proposed approach for the automatic ge ...

Adhesively bonded lap joints of pultruded GFRP shapes

Till Vallée

The importance of Fibre Reinforced Polymers (FRPs) as a material used for civil engineering purposes has grown in the last decade. Especially the introduction of pultrusion at an industrial level as a way to produce big batches of FRP made it possible to o ...
