I was considering the case for a cast-in-place circular manhole. I thought I had seen some projects where conventional reinforcement was replaced entirely by fiber reinforcement. Would wire mesh be suitable for crack control?
I am wondering how to handle the issue of watertightness for a manhole design using fiber reinforced concrete (looking into both steel or synthetic fibers). I have seen that watertightness implies that rebar must be used to control cracking (based on ACI code) but does anyone have experience...
Thank you Doctormo. I have seen the rule of thumb to ignore cohesion for the long term design but I was under the impression that was due to drainage conditions (i.e. loss of cohesion as the soil drains). But since this is a marine project (the retaining system is being installed into the...
I am designing a double wall retaining system and I am wondering what values of cohesion I can use for a marine project consisting of soft to firm silty clay, clay, hard clay till and silt till layers. I found a graph in the geotechnical investigation report that plots cohesion against depth...
Is anyone familiar with determining the driveability of steel sheet piles? This is for a marine environment project and the soil is predominantly clay. I was attempting to relate the energy required against the soil resistance but not sure if there was an actual method.
I am having issues with ensuring the minimum development length for tension between U-shaped stirrups because of a change in the design of a pier cap . Originally, we had the concrete pier cap dimensions following the profile of the road cross section and we had just enough development length...
