ASD Chapter 2, MSJC Code, check compressive and tensile stresses in a reinforced
masonry column: |
|
|
|
|
|
Specified compressive strength of the masonry (f'm - psi or MPa) |
|
|
Moment on column (M - in-lb or N-m ) |
|
|
Axial compressive load on the column (P - lb or N) |
|
|
Eccentricity of the axial compressive load (e - in or mm) |
|
|
Thickness of the column (t - in or mm) |
|
|
Height of the column (h - ft or m) |
|
|
Width of the column (b - in or mm) |
|
|
Area of steel reinforcement (As - in^2 or mm^2) |
|
|
Allowable reinforcement tensile stress (Fs - psi or MPa) |

Area of the column, A = |
|
|
Moment of inertia, I = |
|
|
Radius of gyration, r = |
|
|
Bending stress on the masonry, fb = |
|
|
Allowable bending stress, Fb = |
|
|
Check is fb < or = Fb? |
|
|
Slenderness ratio, h/r = |
|
|
Compressive stress from load, fa = |
|
|
Allowable compressive load, Pa = |
|
|
Allowable compressive stress, Fa = |
|
|
Check is fa < or = Fa? |
|
|
Buckling load, Pe = |
|
|
Check is P < or = Pe/4? |
|
|
fa/Fa + fb/Fb = |
|
|
Is fa/Fa + fb/Fb < or = 1? |
