Thesis (Ph.D.)--Rensselaer Polytechnic Institute, 1995.

The purpose of this research is to present information on the seismic behavior of buried concrete pipelines. In recent earthquakes, concrete pipelines experienced damage rates somewhat higher than those for other types of pipe. Furthermore, most of this damage was observed to occur at the joints. Recognizing that joints are key components, tests were conducted at Rensselaer to determine the characteristics of rubber gasketed concrete pipeline joints. This information is then implemented in a mathematical model to assess the seismic vulnerability of concrete pipelines.Subjects--Topical Terms:

520 $a The purpose of this research is to present information on the seismic behavior of buried concrete pipelines. In recent earthquakes, concrete pipelines experienced damage rates somewhat higher than those for other types of pipe. Furthermore, most of this damage was observed to occur at the joints. Recognizing that joints are key components, tests were conducted at Rensselaer to determine the characteristics of rubber gasketed concrete pipeline joints. This information is then implemented in a mathematical model to assess the seismic vulnerability of concrete pipelines.
520 $a Thirty inch nominal diameter reinforced concrete pipelines, having standard rubber gasketed bell and spigot joints, were tested in our laboratory at Rensselaer. The joint characteristics of interest were the force deformation behavior in axial tension and compression, and the level of deformation or load leading to failure. For the case of axial extension, failure is quantified by the amount of joint extension resulting in leakage. Alternately for compression, failure is quantified by the magnitude of the axial compressive force resulting in crushing at the joints.
520 $a The experimental results are implemented in a mathematical model of a long straight run of segmented pipelines. The segments are discretized into a finite number of elements. The surrounding soil is modeled by axial soil spring-sliders distributed along the model. Finally, the seismic environment is quantified by seismic ground strain.
520 $a Statistical data on pipeline response parameters are obtained using Monte Carlo simulation techniques. For the case of tensile ground strain, the joints accommodate nearly all of the imposed deformation and hence are vulnerable to leakage. For the case of compressive ground strain, the joints are subject to high compressive forces which might lead to the crushing of these joints and hence, leakage. Based on these results, fragility curves are established. These results are benchmarked against the observed water transmission pipe damage in Mexico City occasioned by the 1985 Michoacan Earthquake.
