Effect of seismic forces on design of joint seals for hydraulic structures

摘要

The design of seals for contraction joints must withstand the anticipated displacements of a unit of the structure during an earthquake, as determined by dynamic computations or model tests and allowing for the hydrodynamic pressure of the water. For the determination of rational types and widths of joint, and also their spacing in the structure, special investigations (analytical and model) should be carried out.
