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.

Great product. Delivers as promised. Easy to use. Provides the plan reviewer with "back up confidence" in the structural components.

The Meca Wind software has several programs like multi-roof tops for large greenhouses up to 8 crowns that is not found in most structural wind programs. The range of building types is very broad and therefore very helpful. Also with a little skill, the graphics are very clear for permit packages. As a senior level civil/structural P.E. and owner of a consulting firm for 35 years, and personally licensed in 16 States, I am very pleased. John C Raby & Assoc. Inc. Spokane WA.

Last year, I evaluated several programs and selected MecaWind. The user interface is well designed, the program is well documented and, I have had good experiences with user support. Initial, I had difficulty understanding parapet pressure reports and requested clarification. Within a few days, report changes were implemented making the results much more understandable. I recommend MecaWind.

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.

MORE

MecaWind
Software

MecaWind is a cost effective program used by Engineers and designers to perform Wind calculations per ASCE 7-10 and ASCE 7-16.  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 conrol at their fingertips to customize their output to suit their needs.

MORE

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.

MORE

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.

MORE

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.

MORE

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.
