Prepared by the Pipeline Planning and Design Committee and the Underground Pipeline Asset Management Committee of the Pipeline Division of ASCE This manual provides a general overview of methods used in placing utility cables belowground, including formal underground conduit systems and relatively low-cost direct-buried facilities—with an emphasis on cost-effectiveness and space efficiency. Belowground Pipeline Networks for Utility Cables describes past practices, as well as more recent techniques in which individual pipes or ducts may be advantageously deployed in conjunction with direct-buried cables. Related design, construction, and operational requirements and guidelines are provided, along with analyses of topics including: underground conduit systems; direct-buried systems; cable installation methods in ducts; hybrid belowground cable networks; and status of belowground cable networks. Providing both introductory and specific design and construction information to support the implementation of a proposed hybrid belowground cable network, this book will be valuable to new and experienced engineers involved in road and community construction, utility owners, contractors, municipalities, and project owners.

Prepared by the Technical Committee on Composite Construction of the Structural Engineering Institute of ASCE. This report synthesizes the existing information on hybrid coupled wall (HCW) systems into helpful recommendations pertaining to their seismic analysis and design. HCW systems are lateral-force-resisting systems composed of reinforced concrete walls coupled by steel beams. Extensive research has shown that HCW systems possess the necessary combination of stiffness, strength, and toughness for application in regions of moderate to high seismicity. This book offers two methods for system design: a prescriptive method based on linear elastic analysis and an all-purpose performance-based method that can be used in conjunction with linear or nonlinear analysis techniques. Guidelines for preliminary system proportioning are also provided along with recommendations for component design. This book is valuable to engineers and allied professionals involved in seismic analysis.
