Eventually, the lack of updates became problematic, and the AISC released Allowable Strength Design
as a replacement for Allowable Stress Design with the 14th edition of the SCM.
There has been an ongoing development from allowable stress design to ultimate strength design
(USD) and to the present performance based design (PBD) of RC buildings.
The topics include buckling and collapse of corroded pipes, pipeline inspection and subsea repair, fiber optic monitoring systems, reliability-based strength design
of pipelines, marine traffic risk assessment, consequences of failure modeling for oil and gas spills, and oil spill response plan.
This system is based on three components designed AISI regulations limit state method (LSD), the load and resistance factor (LRFD); Allowable Strength Design
(ASD) is permitted ,
The basis for the flexural strength design
methodology of concrete member with non-metallic reinforcement is the balanced reinforcement ratio [rho].
