H&R Resources Centrix v390.06

Centrix is a centrifugal fan selection program that enables a fan manufacturer to select, design, cost and quote fans for applications. This program does in a couple of minutes what an experienced fan engineer would take many hours to design and cost!

Aerodynamic designs and a nominal range of sizes are entered into the program by H&R Resources. These designs are usually provided by the purchaser. H&R Resources can provide fan aerodynamic design criteria if required. The aerodynamic design is what gives a particular fan its volume, pressure and power characteristics. A single aerodynamic design can meet any volume and pressure that you can think of but the size or speed may not be practical due to mechanical limitations (size outside the range or speed outside the range).

The mechanical design must consider:

• Impeller stresses - dependent on speed, temperature, thickness and material selection.
• Casing thickness - dependent upon fan diameter, pressure and noise breakout.
• Shaft design - dependent upon impeller weight, belt or coupling load, motor torque, fan arrangement, temperature etc.
• Bearing selection - dependent on shaft size and loads and rpm.
• Pedestal design - dependent on fan diameter, power and rpm.

Centrix selects a standard size of aerodynamic design and calculates all the above factors (and more). For example a particular fan selection may not be suitable for belt drive because the bearings can't take the load and larger bearings can't be used because of rpm limitations. However the same fan could be direct coupled arrangement 8 with no problems due to the much lower load. Also Arrangement 7 shaft and bearings can often be used when an arrangement 8 shaft can't. Shaft critical speed is easily calculated by Centrix. If you have ever been unable to balance a fan in service and it vibrates like crazy then you probably have a shaft critical speed problem. Did you know that in overhung fans (arrangements 1, 2, 8, 9) the shorter the distance between the bearings the higher the critical speed is and the larger the impeller overhang from the inboard bearing the lower the critical speed is. The shaft critical speed should always be higher than the fan running speed by a margin of at least 25%. Centrix gives a warning when the critical speed is below 35% margin. Ever had a start up problem? Centrix calculates the starting time and gives warnings alerting you to investigate the use of a larger motor or higher staring torque. Need a speed versus torque curve? Get one from Centrix with dampers open or closed. Centrix enables the user of the software to interact with the program and mechanically design the fan. From this point of view it is invaluable as a design aid and also as a training tool.

IRIS Instruments Comsys Pro v06.03.00

Comsys Pro is a program allowing to control a SYSCAL Pro-Switch resistivity-meter in multi-electrode mode, from a PC. This software is especially dedicated for monitoring applications as a running step can be defined to run some sequences in an automatic way and the data are continuously transferred into the computer (so, no memory limitation).

The main functions of the Comsys Pro software are the following ones:

• Use any type of sequence (2D – 3D – surface/borehole).
• Modes available - Standard measurement; Spontaneous Polarization measurement; High speed (150 ms injection time) measurement.
• Measurement and storage of the grounding resistance values.
• Real time data (resistivity - chargeability) visualization.
• Continuously data storage during acquisition into the computer.
• Display of the estimated time remaining of the current sequence.
• Graphical visualization of the current measuring quadripole.
• Creation of a script for automatic sequence running (resistivity monitoring).

IRIS Instruments Electre Pro v02.02.00

The Electre Pro is a program allowing creation of 2D/3D-surface/borehole measurement sequences for the SYSCAL Pro-Switch resistivity-meters. It allows the user to create automatically (with an estimated maximum investigation depth specified by the user) or manually, some sequences of measurements with many possibilities:

• Use of any type of standard electrode arrays (dipole-dipole, reciprocal Schlumberger-Wenner, pole-dipole forward & reverse, cross diagonal pole-pole …
• Definition of the levels of investigation with the possibility of multi-spacing configuration for data quality improvement.
• Optimization of sequences for higher acquisition speed (the optimization process can add some measurements (gapfiller quadripoles) that can be rejected after acquisition (by the PROSYS II software).

The Electre Pro allows also to import any type of sequences, manually created in a ″txt″ file, in the case of a specific user application. A graphical picture of the created sequence(s) is providedso as to visualize the distribution of the data points that will be measured. Animation can be run to visualize the successive quadripoles of measurement of the created sequence.

CSI SAP2000 v15.0.0

CSI XRevit v2012.0

XRevit allows data exchange between ETABS v9.7.3/SAP2000 v15.1.0/1 and Autodesk Revit Structure 2013. XRevit supports true round-tripping, specifically - four different workflows of data interchange:

• Exporting from Revit Structure to create a new ETABS/SAP2000 model.
• Exporting from Revit Structure to update an existing ETABS model.
• Importing from ETABS/SAP2000 to create a new Revit Structure model.
• Importing from ETABS to update an existing Revit Structure model.

XRevit supports both 32-bit and 64-bit versions of Revit Structure 2013. XRevit is only compatible with ETABS v9.7.4 and SAP2000 V15.1.0/1

CSI ETABS v9.7.4

For nearly 30 years, ETABS has been recognized as the industry standard for Building Analysis and Design Software. Today, continuing in the same tradition, ETABS has evolved into a completely integrated building analysis and design environment. The system built around a physical object based graphical user interface, powered by targeted new special purpose algorithms for analysis and design, with interfaces for drafting and manufacturing, is redefining standards of integration, productivity and technical innovation.

The integrated model can include moment resisting frames, braced frames, staggered truss systems, frames with reduced beam sections or side plates, rigid and flexible floors, sloped roofs, ramps and parking structures, mezzanine floors, multiple tower buildings and stepped diaphragm systems with complex concrete, composite or steel joist floor framing systems. Solutions to complex problems such as panel zone deformations, diaphragm shear stresses, and construction sequence loading are now at your fingertips.

ETABS is the solution, whether you are designing a simple 2D frame or performing a dynamic analysis of a complex high-rise that utilizes non-linear dampers for inter-story drift control.
