Maximum Seismic Moment Solution

STEP 0: Pre-Calculation Summary

Formula Used

Maximum Seismic Moment = ((2/3)*Seismic Coefficient*Total Weight of Vessel*Total Height of Vessel)
M_s = ((2/3)*C*ΣW*H)
This formula uses 4 Variables

Variables Used

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.
Seismic Coefficient - Seismic Coefficient is a measure of the intensity of the seismic shaking that is experienced in an area during an earthquake.
Total Weight of Vessel - (Measured in Kilonewton) - Total Weight of Vessel with Attachment widely depends on its size, material, and function.
Total Height of Vessel - (Measured in Millimeter) - Total Height of Vessel can vary widely depending on its design and size.

STEP 1: Convert Input(s) to Base Unit

Seismic Coefficient: 0.093 --> No Conversion Required
Total Weight of Vessel: 50000 Newton --> 50 Kilonewton (Check conversion here)
Total Height of Vessel: 15 Meter --> 15000 Millimeter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M_s = ((2/3)*C*ΣW*H) --> ((2/3)*0.093*50*15000)

Evaluating ... ...

M_s = 46500

STEP 3: Convert Result to Output's Unit

46500 Newton Meter -->46500000 Newton Millimeter (Check conversion here)

FINAL ANSWER

46500000 ≈ 4.7E+7 Newton Millimeter <-- Maximum Seismic Moment

Height of Lower Part of Vessel

LaTeX Go Height of Lower Part of Vessel = Wind Load acting on Lower Part of Vessel/(Coefficient depending on Shape Factor*Coefficient Period of One Cycle of Vibration*Wind Pressure acting on Lower Part of Vessel*Outside Diameter of Vessel)

Height of Upper Part of Vessel

LaTeX Go Height of Upper Part of Vessel = Wind Load acting on Upper Part of Vessel/(Coefficient depending on Shape Factor*Coefficient Period of One Cycle of Vibration*Wind Pressure acting on Upper Part of Vessel*Outside Diameter of Vessel)

Diameter of Anchor Bolt Circle

LaTeX Go Diameter of Anchor Bolt Circle = ((4*(Total Wind Force acting on Vessel))*(Height of Vessel above Foundation-Clearance between Vessel Bottom and Foundation))/(Number of Brackets*Maximum Compressive Load on Remote Bracket)

Load on Each Bolt

LaTeX Go Load on Each Bolt = Stress in Bearing Plate and Concrete Foundation*(Area of Contact in Bearing Plate and Foundation/Number of Bolts)

Maximum Seismic Moment Formula

What is Design Basis of Vessel?

Design Basis of a Vessel is the set of documents which defines the design, construction, and operation of the vessel. It includes information such as the vessel's intended purpose, design features, materials, safety features, operating environment, system layout, and operating conditions. The Design Basis also outlines the regulatory requirements and industry standards to which the vessel must comply.
