direct stress การใช้

• This is normally derived from a combination of earthquake data, borehole breakout analysis, direct stress measurement and the analysis of geologically young fault networks.
• The direct stress is transferred from the concrete to the bar interface so as to change the tensile stress in the reinforcing bar along its length.
• The direct stress is transferred from the concrete to the bar interface so as to change the tensile stress in the reinforcing bar along its length, this load transfer is achieved by means of bond ( anchorage ) and is idealized as a continuous stress field that develops in the vicinity of the steel-concrete interface.
