Fatigue Design of Steel and Composite Structures (eBook)

Alain Nussbaumer is professor of steel construction (laboratory ICOM) at the Swiss Federal Institute of Technology in Lausanne (EPFL). He is a member of CEN TC 250-SC3 and chairman of the Swiss committee SIA 263 on steel structures. He is a member and the former chairman of the technical committee TC6 - Fatigue of ECCS. Luís Borges is a structural engineer at BG Consulting Engineers Ltd., Lausanne. He holds a doctoral degree from EPFL in the domain of fatigue of tubular bridges and is a specialist for steel and steel-concrete composite structures. He is a member of the technical committee TC6 - Fatigue of ECCS. Laurence Davaine is a senior engineer at France's national railway company (SNCF) and is a specialist for steel and steel-concrete composite bridges. She holds a doctoral degree from the French National school of Bridges and Roads (ENPC) in the domain of stability of plated girders for bridge applications. She is a member of the technical committee TC6 - Fatigue of ECCS.
