Large Deflection Analysis Of Laterally Restrained Reinforced Concrete Slabs, Satwant Singh Rihal

Civil Engineering ETDs

This dissertation is an attempt to analytically predict the large deflection behavior of orthogonally reinforced concrete slabs. The problem considered is that of a laterally restrained, simply supported square slab under uniform loading. The range of loading considered is from zero load to the load at which yielding first commences in the steel reinforcement.

This problem is first formulated using the classical large deflection theory of homogeneous plates. This formulation is based on a constant overall stiffness for the entire slab.

A modified large deflection theory is next developed for reinforced concrete slabs. In this theory concrete on the tension …

Military Environics - Water And Waste, James Anthony Mahoney

Civil Engineering ETDs

This thesis summarizes the activities of the United States Military Services effort, in the areas of water supply, waste water treatment, and solid waste disposal for personnel of the Armed Forces and their dependents. This thesis surveys the state-of-the-art of the present sanitary facilities in the United States and abroad as associated with the military environment. Chapter I compares the responsibilities of the military installation engineer to that of a municipal public works director. Discussed are the service laboratories and their locations. Chapter II includes supply, treatment, design, distribution and storage of water. It is concluded with a reference section …

Shock Shields, Asbjorn Kvammen Jr.

Civil Engineering ETDs

A series of tests was conducted to obtain information concerning the effectiveness of a shock shield of reinforced concrete between ground surf ace and a buried structure as a means of reducing the shock transmitted to the structure due to airblast loading. Two shock shields were used. The diameter of both shields was 20 inches and the thicknesses were 6 inches and 2 feet. The structure was 20 inches in diameter with a thickness of 5 feet. Tests were performed in a 2- by 40-foot shock tube without shock shield and structure, with structure only, and with different thicknesses of …
