Problems solved by technology
The invention discloses a computing method of a secondary axis force of a prestress bottom plate. The computing method includes 1) computing equivalent precompression Npc0 of end concrete of the bottom plate according to tension control stress and area of end prestressed reinforcing bars of the prestress bottom plate; 2) computing coefficient beta according to the thickness H and the length L of the bottom plate, the foundation horizontal resistant coefficient Cx and the concrete elastic modulus E; 3) computing the secondary axis force Nr of the prestress bottom plate, wherein the unit of the Nr is N. The computing method is used for computing the secondary axis force caused by the foundation horizontal resistance, and with the computing formula given in this method, the secondary axis force of various sections in the concrete prestress bottom plate can be conveniently computed, and sufficient reference can be provided for engineering design and computing.
