PERFORMANCE OF CARDBOARD CARTON FORMS Abstract: Cardboard carton forms (void boxes) are commonly used to form the void space between the bottom of grade beams and slabs over expansive soils. However‚ other than laboratory compression tests and 100% humidity tests‚ there is little documentation for the actual performance of these boxes in place. This paper summarizes field tests done in an attempt to simulate actual conditions to answer the following questions: • Do the boxes deteriorate at

BRIDGE CROSSINGS WITH DUCTILE IRON PIPE ® BRIDGE CROSSINGS WITH DUCTILE IRON PIPE Introduction The Ductile Iron Pipe Research Association (DIPRA) periodically receives requests from engineers and contractors concerning recommendations on the design and/or installation of pipelines spanning waterways‚ highways‚ and railroads. Because the variables involved in such installations present numerous alternatives and challenges for designers and contractors‚ DIPRA does not provide recommendations

derivation of a closed-form solution for the fourth-order partial differential equation governing plate deflections in the polar coordinate system. The series solution developed in this study is not only very stable but also exhibits rapid convergence. To demonstrate the convergence and accuracy of the present method‚ several examples with various sector angles are selected and analyzed. Deflections and moments of example sector plates by the proposed solution are compared with those obtained by other

workplace in the future. Not all of the topics can be defined in 10 pages. So the topics that follow are ones that I found importance in and were used very frequently to solve the problems in this semester. The topics to come are Shear Stresses for Beams in bending‚ Castigliano’s Theorem‚ Distortion Energy Theorem for Ductile Materials‚ Mechanics of Power screws‚ and Fatigue loading

clamped into a loading rig such that it was vertical from the side view. The loading rig connected to the portal frame such that there was vertical load at the centre of the beam and horizontal load at the top of a column. There were two gauges‚ one to measure the vertical deflection and the other‚ the horizontal deflection. A set square was also used in the experiment. PROCEDURE The loading rig was inspected for

Objective: To observe the two principal axes in a beam with unsymmetric cross sections; and make comparison between the theoretical and actual behavior in bending of two unsymmetrical section cantilevers: 1. An equal angle with one axis of symmetry. 2. A Z section completely unsymmetrical. Apparatus: Vertical cantilever system‚ dial gauges‚ standard weight‚ hanger‚ cantilever beams of L and Z section. Procedure: 1. Mount up a beam section on the vertical cantilever system and measure
