LOAD CARRYING CAPACITY OF THE MANITOU BRIDGE
The Manitou Bridge is a 40 meter long, 3-span open spandrel arch bridge in the recreation area of Toronto Island. This report describes the tests undertaken to obtain a realistic estimate of its load carrying capacity. The response of the structure to both vehicular and pedestrian loads was monitored through deflection transducers, uni-axial temperature compensated electrical resistance strain gauges and temperature gauges. The data from the strain gauges and deflection transducers were recorded through a computer based multi-channel data acquisition system. The tests included: a temperature study of the bridge, load testing to determine the capacity of the bridge to carry overall vehicle weights, load testing of the deck slab and floor beams to determine their capacity to sustain individual wheel loads; and testing of the cantilever overhang of the deck slab to test its capacity to carry pedestrian load.
