SiWIM Bridge assessement
Bridge failures can threat lives and are thus unacceptable. Optimized assessment of existing bridges, particularly if they are old, deteriorated and suffering from reduced carrying capacity, requires as accurate inputs as possible. An effective option is to apply realistic, site-specific traffic loads and to calibrate the analytical model of the bridge according to the measured bridge response. SiWIM® system was designed to provide such information.
Growth in domestic and international commerce.
SiWIM® provides two types of essential information to improve bridge safety analysis. Firstly, it collects traffic data and secondly, it identifies the true behaviour of bridges (through influence lines and load distributions), a crucial parameter to convert properly traffic loads into load effects (axle loads into moments and shear forces).
