RISA Technologies Launches RISA-3D Version 7.1 Software Package

Pradyut Kr. Roy, Managing Director, RISA Technologies Pvt. Ltd. Kolkata

RISA Technologies launched its latest version of RISA-3D versionof RISA-3D version 7.1 software in package in India May 2007. It uses most accelerated Sparse Solver which is 100 time faster than the earlier used Skyline Solver and making RISA-3D the future of structural analysis. RISA-3D V7.1 includes Indian Design Code for Steel (IS-800), Concrete (IS-456:2000), Seismic and Wind (IS-1893:2002 and IS-875 Part-III), Built in Indian Load Combination Generator, Indian Response Spectra, Automatic approximation of K factors and other international design codes like IS, US, BS, EURO, CAN, AUS, NZ for Steel and Concrete both. RISA-3D V7.1 incorporates the new direct analysis methods of AISC 13thEdition. This version allows users to design for either the ASD or LRFD requirements of this new steel code. RISA-3D V7.1 is available in India within an unbelievably low price brackets.

It’s really appreciable that within a short span of time RISA became so popular that it has been gladly accepted and extensively used by the major design consultants in India as well as in other country like: M N Dastur & Co., SIEMENS-VAI, TATA, SAIL-CET, MECON, L&T, Technip-KTI, Fluor, Bechtel, Jacobs, ABB, Parsons, Aker Kvaerner, Foster Wheeler, Black & Veatch, ALSTOM, NeilSoft, United Conveyor, GE Technologies, Hi-Tech Export, MEHRO Consultants, HOWE India, Unity India, Cethar Vessels, Kiran Consulting Engineers etc and many more engineering colleges and research centers.

RISA-3D V7.1 now offers 8-node solid element which opens a whole new range of modeling and analysis possibilities with SOLID ELELEMENT very easy and faster way it never happened in any other software. This new element combined with RISA-3D’s automatic meshing features opens up a whole new world of modeling and analysis possibilities!

RISA-3D has become most popular and largely used software in USA due to its user-friendliness and interactiveness. User friendliness is what makes this award-winning software such a powerful tool for the analysis, design and optimization of all types of structures and all common structural materials. RISA-3D has a very Clean and Comprehensive CAD-like graphic drawing/editing capabilities that let you draw, modify and load elements as well as snap, move, rotate, copy, mirror, scale, split, merge, sub-mesh, delete, apply, etc. It also supports real spreadsheets with cut, paste, fill, math, sort, find, etc and there is a dynamic synchronization between spreadsheets and views so you can edit or view any data in the plotted views or in the spreadsheets.

RISA-3D also can

• Import DXF, RISA-2D, STAAD and ProSteel 3D files
• Export DXF, SDNF and ProSteel 3D files
• RISA is providing the analysis and design link to Autodesk’s premier building modeling package: REVIT Structure. Apart from the rich graphics and spreadsheet facilities as modeling features, it has got a number of powerful solvers for analysis of
• P-Delta effects, Dynamic analysis
• Response spectra analysis using Gupta, CQC or SRSS mode combinations.
• Physical member modeling that does not require members to be broken up at intermediate joints
• State of the art 3 or 4 node plate/shell elements, sub mashing and auto mashing.
• Accurate analysis of tapered wide flanges­—web, top and bottom flanges may all taper independently.
• Multiple simultaneous moving loads for bridges, cranes, etc.
• Tensional warping calculations of stiffness, stress and design.
• Enforced joint displacements.
• 1-Way members, for tension only bracing, slipping, etc.
• 1-Way springs, for modeling soils and other effects.

RISA-3D’s result presentations are unique

• Graphic presentation of color-coded results and plotted designs
• Color contours of plate stresses and forces with quadratic smoothing, the contours may also be animated
• Spreadsheet results with sorting and filtering of: reactions, member & joint deflections, beam & plate forces/stresses, optimized sizes, code designs, concrete reinforcing, material takeoffs, frequencies and mode shapes.
• Standard and user-defined reports.
• Graphic member detail reports with force/stress/deflection diagrams and detailed design calculations and expanded diagrams that display magnitudes at any dialed location.
• Saved solutions quickly restore analysis and design results.
