Plain Concrete Manhole Cover
Plain Concrete Manhole Cover
(OP)
I need to determine the plain concrete strength of an existing 4" thick 24" diameter concrete tank cover in flexure due to a 500 lbs load at the center. Chapter 22 commentary (R22.2.2) indicates that plain concrete should be limited to members that are primarily in a state of compression. However, section 22.5 provides the nominal moment strength of plain concrete. Is it acceptable to use equation 22.5 to determine its strength?
Any suggestions will be appreciated
