How to calculate the shear force of a column? Can you give an example of calculating the shear span ratio of columns?

Shear span ratio of column a = m/(v× h0); ?

M column end bending moment;

Shear force at the bottom of V-shaped column;

H0 column effective height;

There are such cases: M=V×(H/2), h: the clear height of the column;

So the shear span ratio comes out with a familiar formula: A=H/(2*h0).

The formula of shear force caused by load is: shear force Q =-(the resultant force of all loads in Q direction). The shear force at one end of the column caused by a certain bending moment is M =M/h, and the resultant shear force on the column is 0. (h is the calculated length of the column) Pay attention to the sign superposition of shear force caused by load and shear force caused by bending moment.

Extended data:

Frame-shear wall structure is a structure with appropriate shear walls in the frame structure. It has the advantages of flexible plane layout, large space and large lateral stiffness of frame structure. In the frame-shear wall structure, the shear wall mainly bears the horizontal load, and the vertical load is borne by the frame.

Reinforced concrete wallboard can bear vertical and horizontal forces. It has great rigidity and good spatial integrity. The edges and corners of beams and columns are not exposed indoors, which is convenient for indoor layout and use. Shear wall structure is the most widely used structure in high-rise residential buildings.
