A systematic approach to estimating traffic load effects on bridges using weigh-in-motion data

Alain Nussbaumer, Manfred Hirt, Matthew James Sjaarda

In contrast to the Swiss load model used for new bridge structures (SIA 261), which has roots in a Europe-wide weigh-in-motion (WIM) study and considers the full design life of new structures, the model for existing structures (SIA 269) from 2005 is derive ...

Size effect of welded thin-walled tubular joints

Alain Nussbaumer, Manfred Hirt

This paper clarifies the terminologies used to describe the size effect on fatigue behaviour of welded joints. It summarizes the existing research on size effect in the perspective of newly defined terminologies. It identifies knowledge gaps in designing t ...

A stethoscope for testing of bridges

Alain Nussbaumer, Manfred Hirt, Michel Thomann

Beim Überprüfen der Tragsicherheit einer bestehenden Brücke können dank Messungen die zur Berechnung der Beanspruchung entwickelten Modelle kalibriert werden. Im vorliegenden Aufsatz wird ein neues System von Dehnmessstreifen vorgestellt, welches den erfor ...
