Evaluation method of coupling means bending bear moment to bind the earth retaining wall and foundation slab.

摘要

PROBLEM TO BE SOLVED: To design more economical coupling means which couples an earth retaining wall and a foundation slab by preventing a bending moment borne by the coupling means from being evaluated excessively.;SOLUTION: A method of evaluating a bending moment M_wp borne by the coupling means includes: calculating a first bending moment M_WS generated on the earth retaining wall at a position of the same height as an upper surface of the foundation slab by an earth pressure and a water pressure, a second bending moment M_sn around a line intersection of the upper surface of the foundation slab and the earth retaining wall by force in the vertical direction generated on the earth retaining wall, a third bending moment M_S generated on the earth retaining wall at the position of the same height as a lower surface of the foundation slab, and a fourth bending moment M_QS around the line intersection by shear force generated on the earth retaining wall at the position of the same height as the lower surface of the foundation slab; and calculating M_wp by an equation M_wp=M_WS+M_sn-M_S-M_QS.;COPYRIGHT: (C)2013,JPO&INPIT
