Notes
  • Reactions for a portal frame with fixed bases and a horizontal concentrated load at beam level.
  • The bending moment M is the value at the column base and MB the value at the column top. It varies linearly along the column, so M + MB = Hh.
  • The horizontal load P acts at beam level.
  • M_A is the bending moment at the column base.
