OUR SOFTWARE INNOVATIONS

MecaStack

MecaStack stands as the most widely utilized software globally for the design of self-supported and guy wire supported steel stacks. Our user-friendly Windows-based interface enables designers to efficiently model a stack with complete control over the codes used for Along Wind, Across Wind, Stress, and Fatigue. Additionally, the software allows for the customization of load combinations and factors, providing flexibility and precision as per the specific project requirements.

MecaWind

MecaWind is a highly efficient program that engineers and designers rely on to conduct Wind calculations per ASCE 7-22, 7-16, 7-10, & 7-05 as well as the Florida Building Code. The user-friendly nature of the program, coupled with its ability to generate professional-looking outputs containing all necessary wind calculations, makes it a standout choice. Moreover, users have extensive control at their disposal to tailor the output to their specific requirements, enhancing the overall usability and effectiveness of the program.

MecaLug

MecaLug is an intuitive and user-friendly software program designed to effectively design and analyze lifting lugs per ASME BTH-1 "Design of Below-the-Hook Lifting Devices." Additionally, the program offers an advanced capability to apply these lugs to a lifting system and analyze the corresponding loads experienced by the crane, cable, and lugs - thereby functioning as an all-in-one lifting design software.

Wind Examples E-Book

Our new e-book offers a comprehensive set of wind load calculations, demonstrating the process of calculating wind loads per ASCE 7-16 and ASCE 7-12 in a clear and detailed manner. Furthermore, the e-book provides a valuable comparison of the different methods within each standard, as well as a detailed analysis of the results obtained from ASCE 7-16 versus ASCE 7-22.

OUR ENGINEERING SERVICES

SELF SUPPORTED STACK DESIGN

Meca has designed many different types of self supported steel stacks, ranging in height from 6 m (20ft) to 100 m (328 ft.). Some special design considerations we experienced have included:

  • Single Piece Lift of Stack
  • Special Breech Openings
  • “Piggy Back” Stacks
  • Vibration Design
  • Retrofit of Existing Stacks

GUY WIRE SUPPORTED STACK DESIGN

Meca has designed many guy supported stacks ranging from 15 m (50 ft.) to 167 m (550 ft.) in height. We have performed the following types of special designs:

  • Low Temperature Design (Ambient & Cryogenic)
  • Unique Guy Arrangements
  • Tandem and Piggy Back Stacks
  • Single Piece Lift of Stack (sometimes done from multiple lift points)

DERRICK SUPPORTED STACK DESIGN

We have extensive experience designing derrick supported stacks:

  • 3 Sided or 4 Sided
  • Pipe Members
  • Flat Faced
  • Demountable

FINITE ELEMENT ANALYSIS

Finite element analysis does not always have to be expensive. We encounter certain types of problems repeatedly involving stacks, piping, pressure vessels, etc.. Therefore, we have become very adept at building certain geometries for analysis very quickly to provide a cost effective solution.

AIR COOLED HEAT EXCHANGER STRUCTURAL ANALYSIS

Meca has years of experience verifying the structural integrity for air coolers of various types and designs. We also have experience in the verification of box headers and FEA of nozzles.

OUR PERFORMANCE PRODUCTS

DAMPING
PADS

DAMPING
PADS

Meca offers damping pads tailored for stacks, presenting an economical solution typically suitable for stack heights ranging from approximately 50 ft [15.2 m] to 150 ft [45.72 m]. This solution is simple to implement in new stack designs. Damping pads have garnered over 50 years of industry use, establishing a solid reputation for reliability and effectiveness.

TUNED MASS
DAMPERS (TMD)

A Tuned Mass Damper (TMD) is a device that can be incorporated into the top portion of a stack to enhance its damping, effectively mitigating wind-induced vibration. This advanced solution provides a reliable method to suppress vibration, contributing to the overall stability and performance of the stack.

TUNED LIQUID
DAMPERS (TLD)

Meca specializes in the design of Tuned Mass Dampers (TMD) and Tuned Liquid Dampers (TLD). These solutions are commonly applied to stacks that are 150 ft [45. m] and taller. The selection between TMD and TLD is influenced by various factors that determine the most suitable solution for a specific scenario.

We are using the wind load calculation software. Big time saver in otherwise cumbersone and tedious wind calculations using ASCE 7. Would recommend to structural engineers that need to include wind loads on their analysis.

Hands down the best program to calculate wind pressures on a building. Very simple input. Output is for all kinds of structures and situations. The program can calculate pressures on raised buildings on stilts. Simple 3D modeling with pressures drawn with arrows showing exactly what pressure goes where so there is no confusion. Text output file is very detailed and separated by groups to make it very simple to find what you are looking for. Great resource for Engineers and Architects.

I had been designing steel stacks for decades prior evaluating the software for use at the company I work for. I found MecaStack to be incredibly mature, flexible and easy to use. It blew away the competition! It is so much faster than the cobbled together proprietary software, hand calculations, spreadsheets, etc. we used prior to acquiring MecaStack. Favorite features include the graphic representation of the stack as it is designed, the ability to turn across wind analysis on and off, and ease of switching between US and SI units on the fly. WELL DONE!!!
