Welcome to Meca Enterprises
Meca Enterprises is an engineering company developing software for Steel Stack design, Wind Load Calculations and Lifting Lug design. We also provide engineering services on a variety of process equipment (Stacks, Skids, Air Cooled Heat Exchangers, etc.). One of the most common problems that occur with steel stacks is wind induced vibration, and so we also offer cost effective alternatives (i.e. dampers) to address stack vibration (vortex shedding) problems.
WHAT WE DO
INNOVATIONS
Engineering Software
We provide software solutions for Structural Engineers. We offer the only software specifically written for steel stacks in the world and one of the most cost effective wind programs available.
PERFORMANCE
Stack Vibration Dampers
Meca Enterprises offers Damping Pads and Tuned Mass Dampers (TMD) to solve Vortex Shedding problems commonly known as Stack Vibrations.
SOLUTIONS
Engineering Services
We can provide Structural Engineering services for stacks, air coolers and other structures. We are licensed in several states as well as Alberta and British Columbia.

OUR PRODUCTS
MecaStack
Software
MecaStack is the most widely used software in the world for designing self-supported and guy wire supported steel stacks. An easy to use Windows based interface allows designers to quickly model a stack. The user has complete control over the codes that are used for Along Wind, Across Wind, Stress and Fatigue. Load Combinations and factors can be customized as needed.
MecaWind
Software
MecaWind is a cost effective program used by Engineers and designers to perform Wind calculations per ASCE 7-22, 7-16, 7-10, & 7-05. The program is simple to use, and offers a professional looking output with all necessary wind calculations. The user also has a great deal of control at their fingertips to customize their output to suit their needs.
Wind Example
e-Book
Our new EBook provides a detailed set of wind load calculations that illustrate how to calculate wind loads per ASCE 7-10 and ASCE 7-16. In addition, the EBook provides a comparison of the various methods within each standard as well as a comparison in the results obtained following ASCE 7-10 versus ASCE 7-16.
MecaLug
Software
MecaLug is an easy to use software program effective in designing and analyzing lifting lugs per ASME BTM-1 “Design of Below-the-Hook Lifting Devices”. The program also has the added ability of being able to apply those lugs to a lifting system and analyze what loads would be seen by the crane, cable, and lugs. Making it an all-in-one lifting design software.
Damping
Pads
Meca provides damping pads for stacks. Generally these are an economical solution for stack heights from about 50 ft [15.2 m] to 150 ft [45.72 m].
It’s a very easily solution to implement on New Stack designs. Damping pads have been used for about 40 years, and have proven to be very reliable.
Tuned Mass
Dampers (TMD)
A Tuned Mass Damper (TMD) is device that is added to the top portion of the stack that increases the damping of the stack, which will suppress wind induced vibration.
Tuned Liquid
Dampers (TLD)
Meca has partnerships with companies that design Tuned Mass Dampers (TMD) and Tuned Liquid Dampers (TLD). These are typically used on stacks that are 150 ft [45. m] and taller. There are many factors that determine whether a TMD or TLD is more appropriate.
