The new opening bridge over the River Cart at Inchinnan, near Renfrew, carries the principal road from Glasgow to Greenock and other west-coast ports, and is the only bridge over the Cart between Paisley and the Clyde, a distance of 3 miles. It provides an improved and widened navigation channel between Paisley and the River Clyde. The earliest attempt to improve the Cart navigation was made in 1753. The Cart Navigation Trust was formed in 1834, when the present swing bridge was erected over an artificial channel. The financial embarrassments of the Trust led to the undertaking becoming derelict in 1915. In 1920 power was granted to the Burgh of Paisley to improve the navigation-channel at Inchinnan and to replace the old swing bridge by a modern opening bridge. The widened channel has a clear width of 90 ft. and a depth of 21 ft. at high water length of about 250 ft. William Bertram Hall
The subject of this paper is the strength of rectangular slabs, but it is limited to such slabs as have an appreciable thickness coinpared with the span, and more particularly it is limited to slabs of reinforced concrete only. A. Ingerslev
In calculating the strength of plated rolled or built up sections it is usual first to calculate the moment of inertia about the neutral axis and then divide by the distance of the neutral axis from the extreme fibre. W.A. Green
