Calculation title GRP Clamped Shoes & Flange Supports of 3

Calculation objective

The purpose of this calculation is to check the strength of GRP clamped shoes and flange supports.

Calculation method

The following three criteria are to be used to check the strength of GRP clamped shoes and flange supports:1. Weld strength at base plate top surface.

2. Weld strength of support base plate to structural steel (base plate bottom surface).

3. Bending strength of welded attachment at base plate top surface.

Assumptions

The following conditions / assumptions have been used in the calculations:

1. Line method used to calculate linear section modulii of welds.

4. Area of maximum stress for GRP Clamped Shoes and Flange supports is assumed to occur at the base plate interface.

5. Height at which load acts above the TOS for GRP Flange supports is assumed to be the distance to BOP plus 50mm.

6. For high load GRP Clamped Shoes and Vertical Flange Supports, 2/3 of the load is assumed to transfer to each support half.

Dependent Calculations

None.

Conclusions1. Standard Supports are adequate for the maximum allowable loads shown on the drawings.

2. Fillet weld leg length = h (mm). For all weld calculations the throat thickness is used as the weld size (i.e. h / 2 0.5), which is conservative.

3. For weld strength at the base plate top surface for GRP Clamped Shoes the moment of inertia of the H-Section web is added to the gusset plate welinertia.
