MECA MecaWind v2406 Software
 
MECA MecaWind v2406

MECA MecaWind v2406

MecaWind is a wind load calculator software used to calculate wind loads and/or wind pressures on the main wind force resisting system (MWFRS) of buildings and many other structures (Chimneys, Tanks, Towers, Open Signs, Closed Signs, Solar Panels, Rooftop Equipment, Canopy, Bins, Tanks, Silos and Free Standing Walls).  It is based upon the ASCE 7 standard used throughout the United States for design loads, which is published by the American Society of Civil Engineers.  The MecaWind wind load calculator software contains multiple versions of the ASCE 7 standard as well as the Florida Building Code (FBC).  For instance, it includes, ASCE 7-05, ASCE 7-10 and ASCE 7-16, each being a different release of the same standard.  The latest version is ASCE 7-16, and many of the changes found from the ASCE 7-10 version to ASCE 7-16 can be found in this article.  ASCE 7-05 is also included in MecaWind, but this older version of the standard is used less frequently in jurisdictions. However, having it included allows users to evaluate existing structures to the older version of the ASCE 7 standard. MecaWind software is very cost effective, easy to use, and has a minimal learning curve.  The software allows you to perform wind design with ease and is essentially a wind pressure calculator. 


MecaWind calculates wind loads per the ASCE 7 standard, and in that standard there are two basic classifications of structures: Buildings & Other Structures.

A building is just as you would expect, it could be a simple house or storage building or a high rise building. There are many different special classifications of buildings within the ASCE 7 standard, and all of these are covered by the MecaWind wind load calculator software. Below is a list of examples:
  • Enclosed Building
  • Partially Enclosed Building
  • Partially Open Building
  • Open Building
  • Low Rise Building
  • Simple Diaphragm Building
  • High Rise Building
  • L-Shaped Building
There are several different roof types which are addressed in the ASCE 7 standard, and these same roof types are also included as options with the MecaWind wind load calculator software.  Depending upon the specific analysis methods chosen, some of these roofs are not handled by ASCE 7. However, the MecaWind wind load calculator software makes it easy for the user to easily see which roofs are permissible based upon the method that has been selected by the user.

Here are some of the more commonly used roof types: Arched, Domed, Flat, Stepped, Gabled, Multi-span Gabled, Hipped, Mansard, Monoslope and Sawtooth.

MECA MecaLug v1039 Software
 
MECA MecaLug v1039

MECA MecaLug v1039

MecaLug is a Padeye or Lifting Lug Calculation Software package that is used to perform padeye or lifting lug calculations as well as analyze loads acting on padeyes or lifting lugs for a structure or piece of equipment. Several different styles of padeyes or lifting lugs are offered giving the user multiple options in selecting an appropriate lifting lug. There are also several different configurations in the MecLug Software for different equipment and structures. The lifting lug software even has templates for lifting a stack or cylindrical vessel from horizontal to vertical, using either lifting lugs or lifting trunnions. For this special type of lifting of stacks, the lifting lug software considers the multiple angles as the structure rotates from horizontal to vertical in order to find the worst angle on the lifting lugs/trunnions and tailing lug.


MecaLug Standard version is the least expensive version of the software that allows the user to perform Padeye / lifting lug calculations per ASME BTM-1 "Design of Below-the-Hook Lifting Devices”. Engineers often design structures and equipment for extreme wind, seismic and other loading that may never occur; however, in the case of a lifting lug those extreme loads may very well be experienced at the beginning of the equipment life cycle, not in 20+ years down the road. The failure of a lifting lug could very likely put human life in danger in the event of a failure. The lifting lug software allows the user to quickly and accurately analyze Padeye / lifting lugs for a variety of loads.

MecaLug Pro version offers the same features of the standard version of the lifting lug software of analyzing a single lug or trunnion, but MecaLug Pro also has the added benefit of being able to apply those lugs to a lifting system and analyze what loads would be seen by the crane, cable, and lugs. This Pro feature of the MecaLug allows the designer to consider lifting a piece of equipment or structure, and have the software determine the loads acting on each individual lug. The analysis of each lug is then performed by the lifting lug software. The Pro features make MecaLug an all-in-one lifting lug software.

MECA MecaStack v5630 Software
 
MECA MecaStack v5630

MECA MecaStack v5630

MecaStack is steel stack design software that is used to design steel stacks, steel chimneys, flares, exhaust stacks, etc. of a variety of dimensions and attachments. In addition, the software also performs a bending analysis of the stack to aid with the stack lifting design. MecaStack can be used to analyze self supported stacks (free standing) and guyed stacks. Similarly, it can be used for design of steel chimneys or stacks that are braced on a building or other structures by lateral bracing. Above all, the software is very easy to use and extremely versatile at handling a wide range of problems and designs.


Some of the components that MecaStack incorporates are: Ladders and Platforms; Stiffening Rings; Structural Flanges; Damping devices; Flare Tips; Insulation/Refractory/Jacket; Breaches/Nozzles; Piping.

The user has complete control over the design codes that are used for Along Wind, Across Wind, Stress and Fatigue. In addition, the load combinations and factors can be customized as needed or auto-populated per the design code selected.  There are several comprehensive steel chimney design codes available within the MecaStack design software:
  • American Standard: ASME STS-1
  • CICIND
  • Indian Standard
  • British Standard
  • Euro Standard
  • Canadian Standard
  • Brazilian Standard (NBR 6123)
  • ISO 13705 (Formerly API-560)
  • Mexican Standard CFE
Seismic Design Codes. There are several seismic design codes available:
  • Indian (IS1893)
  • UBC 97
  • Manual Entry
  • International Building Code (IBC)
  • Response Spectrum Analysis
  • National Building Code of Canada (NBCC)
  • EuroNorm (EN 1998-6)

MecaStack v5.1.9.7 Software
 

MecaStack v5.1.9.7

MecaStack v5.1.9.7

MecaStack is a stand-alone executable program that performs the overall structural analysis of Self Supported or Guy Wire Supported Steel Stacks. It uses a stiffness matrix to completely model the stack and its loadings, and then applies the appropriate acceptance criteria based upon the user selected design code. The program also calculates the natural frequency of the structure so that the dynamic along wind and dynamic across wind (vortex) loads can be applied to the stack.
