COSS-APP

COSS-APP | Cantilever Overhead Sign Structure Application

Intuitive Graphic User Interface

Our user interface was created to be easy to use. Whether you’re creating complex cantilever overhead tri-chord or quad-chord truss type structures, or tubular (monotubes), COSS-APP has you covered.

Robust Analysis and Design

COSS-APP features allow you to rapidly create your cantilever overhead sign structure (COSS) analytical models using a wide range of options within a friendly user interface. Easily define your parameters and COSS-APP will setup the model for you in Bentley STAAD.Pro® CONNECT Edition or MIDAS CIVIL NX®, leveraging both platforms’ advanced analysis capabilities.

The features included in COSS-APP are the following:

• Truss and arm geometry
  • Tri-chord truss
  • Quad-chord truss
  • Tubular (Round section and 16-sided to 4-sided sections)
  • Dual-chord truss
• Material and sectional properties
• Type of connection (pinned or rigid)
• Type of attachment
  • Sign Panels
  • Dynamic Message Sign or Variable Message Sign panels
  • Catwalk (walkway)
  • Other general attachments
• AASHTO type loads:
  • Permanent Loads
  • Wind Loads
  • Natural Wind Loads
  • Truck-Induced Gust Loads
  • Ice Loads
  • Wind on Ice Loads
• AASHTO type load combinations
• Special feature:
  • Wind-shielding and shading effects due to attachments
  • Fatigue loads
• Industry Standards:
  • American Institute of Steel Construction (AISC)
  • Steel Tube Institute (STI)
  • American Association of State Highway and Transportation Officials (AASHTO)
  • AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals
• Methodology:
  • Load Resistance Factor Design (LRFD)

Comprehensive Model Results

Create models with both graphical and numerical results including robust detailed inputted parameters, giving you and your colleagues full confidence in your design.

Interoperability

COSS-APP integrates with STAAD.Pro’s and MIDAS CIVIL NX® interoperability technology, allowing end-users to access more advanced features, and work collaboratively and collectively thorough the project’s lifecycle.
