Aurelio Muttoni

Aurelio Muttoni is full Professor and Head of the Structural Concrete Laboratory at the Ecole Polytechnique Fédérale de Lausanne (Switzerland). He received his diploma and PhD in civil engineering from the Swiss Federal Institute of Technology, Zurich, Switzerland, in 1982 and 1989, respectively. His current teaching activities focus on the conceptual design of structures, theory and dimensioning of concrete structures as well as bridge design. His research group is active in the following domains: behaviour and design methods for structural concrete, conceptual design of innovative structures, shear in structural concrete, punching shear of slabs, nonlinear structural analysis including its reliability, bond between steel and concrete, aggregate interlocking, fatigue and influence of sustained loading on the concrete strength, mechanical behaviour and design concepts for ultra-high performance concrete, textile concrete and recycled concrete. Aurelio Muttoni was the recipient of the Chester Paul Siess Award for Excellence in Structural Research in 2010 and the co-recipient of the Wason Medal for Most Meritorious Paper in 2014 of the American Concrete Institute. He is a member of the Presidium of fib (International Federation for Structural Concrete), several fib commissions and task groups and has been Project Team Leader for the second generation of EN 1992-1-1 (Eurocode for structural concrete). Aurelio Muttoni is also cofounder and partner of the Muttoni & Fernández consulting office (www.mfic.ch). This office is active in the conceptual design, analysis and dimensioning of load-bearing structure in architecture and civil engineering constructions as well as consulting activities in the field of structural engineering.

Bridge

A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations.

Truss bridge

A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently.

Structural engineering

Structural engineering is a sub-discipline of civil engineering in which structural engineers are trained to design the 'bones and muscles' that create the form and shape of human-made structures. Structural engineers also must understand and calculate the stability, strength, rigidity and earthquake-susceptibility of built structures for buildings and nonbuilding structures. The structural designs are integrated with those of other designers such as architects and building services engineer and often supervise the construction of projects by contractors on site.

Concrete

Concrete is a composite material composed of aggregate bonded together with a fluid cement that cures over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminium combined. When aggregate is mixed with dry Portland cement and water, the mixture forms a fluid slurry that is easily poured and molded into shape.

Reinforced concrete

Reinforced concrete, also called ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars (rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials.
