There is not currently an option for a dual wall stack in MecaStack; however, you can model a dual wall stack as follows: 1)  Model the outer stack diamete...

The "Enter Pipe" option is only a convenience option to use when the stack is fabricated from pipe material, rather than rolled from plate.  For Ex...

When you model as piping, then no stiffness is considered for the piping, the software only adds wind area and weight.  The wind area and weight are assume...

There are not any codes which are very complete when it comes to analysis of vortex shedding on guyed stacks.  There have been very few instances where guye...

The basis for the Baseplate Design in MecaStack is from "Process Equipment Design" by Brownell and Young.  This book is no longer being published,...

MecaStack considers effective length factors (K) for sections of a Self Supported or Guy WIre supported stack, depending upon the boundary conditions at eac...

In the non-linear analysis the user specifies "load steps".  The total load is divided by the number of load steps and then applied.  For example,...

Structural flanges are flanges which are used to splice sections of stack together, rather than using a weld. They are bolted flange assemblies similar to t...

The "Auto Size Turnbuckle" works as follows:​ Cable Load = Breaking Strength / Safety Factor for Guy wires The software finds a turnbuckle that h...

Often the question arises as to whether helical strakes can be considered as stiffening rings in the Stack Analysis.   Generally helical strakes are very t...
