Dynamics of Tall-Building Riser Design, Part 1 of 2: The roles of gravity, volume, and thermodynamics in smart riser design

摘要

Though we have figured out how to build strong tall structures and safely move people inside, challenges of heating and cooling, of moving fresh water in and dirty water out, and of providing fire protection and electricity persist. These are made all the more complicated by a need to defy gravity. This article discusses basics of pipe-riser design and performance, identifies key considerations regarding the use of expansion joints in pipe risers, and explains codes and standards governing the guidance and support of risers.
