Meca can design a Tuned Mass Damper (TMD) to solve your stack vibration problems.
MecaStack is the most widely used software in the world for both self supported and guy wire supported steel stacks.
MECA’S DAMPING PADS OFFER A SIMPLE AND COST EFFECTIVE SOLUTION TO ADDRESSING MANY STACK VIBRATION PROBLEMS.
Flare companies worldwide have overwhelmingly chosen MecaStack as their preferred tool for performing structural design of stacks.
Calculating wind loads on any building per ASCE 7 is a breeze with our MecaWind Software.
Meca supports plant Engineers in evaluating the structural integrity of stacks and to investigate proposed modifications.

Welcome to Meca Enterprises Inc.

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 addressing stack vibration (vortex shedding) problems.

I looked at and tried a lot of programs for calculating wind loads on building structures. I finally settled on... Mecawind because of the graphics and the ease of using the program. I believe this is possibly the best program out there for this application. The other thing that I really like is if you have a question it is answered immediately or if you have a problem it is solved immediately.if you are a structural engineer and looking for a program to quickly calculate wind loads on building structures look no further.read more

Under the category of Other Structures, the ASCE 7 Standard covers, among other shapes, tanks, chimneys, and silos, but... it doesn't specifically address tall, tapered members that are similar to trapezoidal shapes. Recently, however, Meca has added an upgrade which specifically covers this issue and it works very well. This allows engineers using this software to develop accurate wind loads on members such as tapered poles and similar members. Yet another enhancement to great product. It also contains a section that will approximate the natural frequency of a member, which is crucial when determining the gust effect factor of tall, slender, flexible structures.read more

I highly recommend the MecaWind program. The program is easy to use and it does a great job of helping an engineer... visualize the application of the wind loads on the structure. This very useful for teaching young engineers how the loads act on the structure. This program is used on every project in my office.read more

We have a small Engineering firm (only 3 of us) and this program is ideal for us.When our projects require wind... related calculations, this program fills the bill and is straight forward and easy to use.We have a copy of the 1960 Building Code and it is the size of a hymnal. By contrast, the current code consists of volumes of information and requirements for each project. This program simplifies meeting the wind calculation requirements. We have been a long time user of Mecawind and will continue into the future.read more
