Experimental study on mechanical properties of prestressed concrete cylinder pipes (PCCPs) under external load
literature review
general characteristic of PCCPs
how P/S works
ECP LCP
ECP large diameter
evaluate the design method of PCCPs
PCCPs better performance, severe consequences from its failure
5 categories
design, manufacture, construction, operation, maintenance
opeartion has serious consequences
Experimental study is the best choice to investigate the performance and analysis the failure of PCCPs
