To evaluate the contribution of the concrete slab to the shear resistance of composite concrete-steel plate girders, two tests were carried out on one full-scale composite plate girder. The tested specimen was loaded to failure under shear load and positive moment. Vertical deflection of the girder and out-of-plane deflection of the web panels were monitored during each test. Principal strains and their inclination were obtained by instrumentation on the web, flanges, stiffeners, and concrete slab. The observed failure mechanism of the tested specimen is presented using the test results. Nonlinear finite-element analysis of the tested specimen was carried out and calibrated using the tests results. To study a wider range of composite girders, further finite-element models were built with different concrete slab and steel web thicknesses. The experimental and analytical results indicate that the ultimate capacity of the tested composite specimen is higher than what is predicted by the current AASHTO design specifications for a bare steel plate girder. © 2013 American Society of Civil Engineers.

A vertically-adjustable caster wheel apparatus for use on a forklift truck, material handling cart, and the like. The caster wheel apparatus of the present invention provides a yolk frame having a pivot pin connected to and extending through the yolk frame. A wheel frame has one end pivotally connected to the yolk frame and a second end rotatably connected to a wheel. An elastic member has a first retainer connected to one end of the elastic member and a second retainer connected to an opposite end of the elastic member, wherein the first retainer is connected to the pivot pin in the yolk frame to allow the elastic member to pivot with respect to the yolk frame. Means for adjusting the vertical height of the wheel is provided by adjusting the angle of the wheel frame relative to the yolk frame.


A system for converting an existing traffic intersection into an intersection having a roundabout traffic control feature includes a center island framework, one or more splitter island frameworks, and one or more diverter frameworks. The frameworks are secured to the road surface, and fill material is added to free spaces defined in the frameworks to thereby form a center island, one or more splitter islands, and one or more diverters. The system allows a roundabout to be implemented into an existing intersection on a temporary or semi-permanent basis, in a minimal amount of time and without requiring significant construction at the site of the intersection.
