Pankaj Taneja — Tue, 09 Aug 2011 17:12:38 GMT

Design Software for Communication Towers

OpenTower Designer performs comprehensive design and analysis of various types of communication structures such as tapered monopoles, stepped poles, 3-legged or 4-legged self-supporting and guyed towers. OpenTower helps engineers to generate the physical model using parametric setup wizards and categorizes the panels/sections, legs, horizontals, and bracing members with orientations without manual intervention. The structure can easily be edited to achieve the desired shape and configuration.

New Features and Updates

Monopole Reinforcement and Connections

It’s a new feature implemented for all the supported types of poles such as Tapered, Stepped, and Hybrid poles in OpenTower Designer. It has been implemented for all the TIA design standards (EIA/TIA-222-F, TIA-222-G, and TIA-222-H). The monopole reinforcement calculator is also added to allow user to create new reinforcement sections. To access Monopole reinforcement, go to the Section Detail page and navigate through the Reinforcement and Connection page.

Shroud and Conduit

The user has a provision to use the Shroud or Conduit type of encasement for the feeders. This is achieved by creating a different type of continuous attachment from the UPT or include in the standard database. Both shroud and conduits are implemented for monopoles only. The feeders referring to the shroud attachment will be shielded from the wind load calculations and will be included in the Ra factor. Only the self-weight of those feedlines will be considered.

Tower Profile Page - The Tower Profile page has been updated and includes the tower weight (for SST and monopoles) in tower notes, monopole reinforcement tables, and updates to the logo and address details.

OpenTower Designer CONNECT

Tower design re-imagined

Structural modeling, analysis, and design solution for communication towers

We are proud to announce the release of OpenTower CONNECT, a leading structural solution for telecommunication towers. This purpose-built application captures real-life analysis workflows, including modifications, multiple scenario evaluations, foundation checks, and connection designs. It can connect with equipment databases to automatically generate wind and seismic loadings, analyze the structure and produce custom reports. The application’s advanced graphics offer a realistic view of the tower as modeled, including 3D rendering of equipment and feedlines on the tower. The program is offered through’s Bentley’s consumption-based visa licensing program and known as OpenTower Comms Visa.

OpenTower Designer is the next generation of Bentley's Tower product and users of that product will find OpenTower ease to use and follow the tower engineer daily workflow in detail.

Flexible and extendable architecture

OpenTower was developed with an open architecture. Considering changing business trends on modifying existing structures, the application is designed to work with external catalogs and libraries, which can be edited and extended throughout the lifecycle of tower management and re-analysis.

OpenTower includes comprehensive databases, such as appurtenances catalog, bracing library, and truss-leg library. A custom tower catalog is provided for built-up sections, typically used for reinforcing towers. This catalog can be extended by adding new sections and new section profiles. User-provided table (UPT), is an innovative method to create and use user-defined materials, sections, and appurtenances.

With state-of-the art technology and graphics, OpenTower is designed for its openness and user-friendliness.

Increased Modeling Efficiency with Automation and Best-Practices

Engineers can now model lattice towers faster than ever using physical model generation utilities thorough parametric wizards. This includes automatic orientations of all members. It is a physical modeling system, where geometry is defined as a combination of multiple panels, starting from the top.

Discrete and linear appurtenances can be easily attached and viewed through built-in catalogs and an intuitive user interface. OpenTower automatically generates wind, ice, and seismic loads based on TIA 222- Rev F, Rev G, and Rev H standards along with ASCE 07.

The application was designed by practicing engineers and encompasses engineers’ desired workflow and best practices. All the inputs were cleverly structured and screens were reimagined to optimize your work. Discrete appurtenances can be attached through mounts, and feedlines are provided in reference to linear attachments, such as ladders and banjo brackets.

Advanced Capabilities

A OpenTower model essentially becomes a living history of a tower’s lifecycle management through its modification layer and scenario analysis capabilities. The application’s multilayered approach to separate modification layers from the base model, enables users to combine installed model with hierarchical proposed modifications. All modifications are saved for future use.

The application separates loading layer from geometry layer. Users can create any number of load definitions, groups, and configurations with appropriate classifications. A loading layer can then be combined with a geometric layer to create an analysis scenario. Users can analyze and compare as many scenarios as needed to deduce the optimum configuration.

Realistic Graphics and precision modeling

OpenTower adopted “Wysiwyg” philosophy. It promotes precision modeling and offers many powerful capabilities to achieve it. All section profiles, including built-up sections like split-pipe are drawn to scale with appropriate rotation of its major and minor axes. Any object, including discrete and linear appurtenances can be clicked to review its properties. Feedline Tool helps to position the feedlines along the height of the tower by forming and moving feedline stacks on a grid system. The application can automatically form clusters and calculate the effects of shielding. Visualization shows realistic 3D graphics of all modeled equipment on the tower along with geometry.

Powerful Results and Diagrams

OpenTower provides an exhaustive set of post-processing features that includes results and diagrams. It renders leg compression curves, deflection, tilts, twists, axial forces, moments, torsion, and stress diagrams along with dynamic browsing facility for member forces and member stresses at any point of the cross-section on any member at any location for any load case. It displays tables for member-end forces, joint displacements, and support reactions. Users can customize report format through intuitive report generator and export to various formats, including PDF and Microsoft Excel spreadsheets.

Support for Legacy Software and Interoperability

OpenTower can import any RISA Tower or tnxTower model (.eri files). The application generates a STAAD.Pro file that can be used for advanced analysis, like dynamic and buckling analysis, as well as flexible Mat foundation design.

Foundation Design

Engineers can now easily design/check tower foundations with program’s built-in foundation design functionality. It automatically iterates through support reactions for all load combinations to find the critical load combinations for all possible design criterion, including serviceability and ultimate design. Current version of the program supports, pad &pier (isolated) foundation, block foundation, drilled pier foundation, and guy anchor foundation. It greatly increases tower design efficiency.

Question on Modulus of Elasticity of concrete in STAAD

Mark — Sat, 05 Oct 2019 05:56:09 GMT

Hello. How does STAAD compute the modulus of elasticity of concrete (default material properties)?

The default values are:

fcu is 27.58 MPa

E is 21728 MPa

Say I would like to use f'c = 27 MPa, what would be the corresponding E and fcu?

I know that f'c is about 0.8fcu.

Thank you!

How to model sloping parapet walls in RAM Structural System

Pascual Mauricio — Wed, 15 Apr 2020 19:41:34 GMT

Hello,

I have a one-story building with sloping parapets on the exterior walls and flat parapets on an interior portion (see white colored parapets in image below).

Currently, my model has the floor and the roof, with the roof having the deck and beams. I imagine I will need to create another story for adding the parapets, but since all the parapets are at varying heights above the roof, I do not know how to model that correctly. I am wanting to include the parapets in my model due to snow drift on the roof.

Please advise. I have attached my model file as well. Please feel free to try to implement the parapets into the model.
