Variables Used

Stress due to Seismic Bending Moment - (Measured in Newton per Square Millimeter) - Stress due to Seismic Bending Moment is a measure of the internal force that resists deformation or failure of a material when an external force is applied to it.
Maximum Seismic Moment - (Measured in Newton Meter) - Maximum Seismic Moment is the reaction induced in a vessel when an external force or moment is applied to the element causing the element to bend.
Mean Diameter of Skirt - (Measured in Millimeter) - Mean Diameter of Skirt in a vessel will depend on the size and design of the vessel.
Thickness of Skirt - (Measured in Millimeter) - Thickness of Skirt is typically determined by calculating the maximum stress that the skirt is likely to experience and their must be sufficient to resist the weight of the vessel.

STEP 1: Convert Input(s) to Base Unit

Maximum Seismic Moment: 4400000 Newton Millimeter --> 4400 Newton Meter (Check conversion here)
Mean Diameter of Skirt: 601.2 Millimeter --> 601.2 Millimeter No Conversion Required
Thickness of Skirt: 1.18 Millimeter --> 1.18 Millimeter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

f_{bendingmoment} = (4*M_s)/(pi*(D_sk^(2))*t_sk) --> (4*4400)/(pi*(601.2^(2))*1.18)

What is Design Load?

Design load is the total load that a structure, component or system must be designed to bear. This load is used as the basis for designing a structure and is typically based on the maximum anticipated load that the structure will be subjected to during its life. It is often used to determine the size and strength of the components that make up a structure. Design load can include environmental loads such as wind, snow, ice and seismic activity, as well as operational loads such as traffic and equipment.

How to Calculate Stress due to Seismic Bending Moment?

Stress due to Seismic Bending Moment calculator uses Stress due to Seismic Bending Moment = (4*Maximum Seismic Moment)/(pi*(Mean Diameter of Skirt^(2))*Thickness of Skirt) to calculate the Stress due to Seismic Bending Moment, Stress due to Seismic Bending Moment is formed when seismic waves travel through a vessel and if the stresses are not relieved, the vessel may sustain structural damage or even disintegrate. Stress due to Seismic Bending Moment is denoted by f_{bendingmoment} symbol.
