Seismic Risk Assessments of Small Earth Dams
A procedure has been developed which attempts to assess the risk of damage or failure of small earth dams and embankments when subjected to seismic input motions. The procedure is based...

Philosophy for Treatment of High-Pressure Natural Gas Pipelines at Active Fault Crossings
Natural gas from fields in the overthrust belt of southwest Wyoming will be collected and transported to Southern California. The proposed Kern River Pipeline will transport gas to Daggett,...

Simplified Numerical Analysis on Earthquake Response of Irregularly Bounded Surface Layer
Evaluation of seismic response of a soft surface layer is the essence in a design of a lifeline in this layer. For this purpose, a quasi-three dimensional ground model was developed by...

Pressure-Treated Wood Effect on Marina Environment
