RBS produces a wide range of Pre Engineered Building
systems including clear span, rigid frame, modular rigid frame, tapered beam and lean-to. All are available in standard or long span options. Crane support systems, and mezzanines can also be included as part of the complete building package. Pre Engineered building can be designed as per client requirement with optimization of steel and its design.RBS Pre Engineered Building System a custom design to meet client requirement. The basic building parameters are:
Pre Engineered Building Length:
- The distance between the outside flanges of end wall columns in opposite end walls is considered the building length.
- End bay length is the distance from outside of the outer flange of end wall columns of center line of the first interior frame columns.
- Interior bay length is the distance between the center lines of two adjacent interior main frame columns.
Pre Engineered Building height is the Eave height which usually is the distance from the bottom of the main frame column base plate to the top outer point of the eave strut. When columns are recessed or elevated from finished floor, eave height is the distance from finished floor level to top of eave strut.Roof Slope (x/10):
This is the angle of the roof with respect to the horizontal. The most common roof slopes are 1/10 and 1/2-0. through any practical roof slope is possible as per customers requirement.
RBS Pre Engineered building system are designed for the following minimum loads. The metal building will be design with Indian Standard codes and American Codes as required. The building loads will be calculated with the required code as suggested.Design Codes:
Following are the main design codes generally used:
- AISC : American institute of steel construction manual
- AISI : American iron and steel institute specifications
- MBMA : Metal building manufacturers code
- ANSI : American national standards institute specifications
- IS : Indian standards
- Design Method: Allowable stress design method is used as per the AISC specifications.
- Deflections: Unless otherwise specified, the deflections will go to MBMA, AISC criteria and standard industry practices.
- Primary Framing: Moment resisting frames with pinned or fixed bases.
- Secondary Framing: Cold formed Z sections or C sections for purlins or girts designed as continuous beams spanning over rafters and columns with laps.
- Longitudinal Stability: Wind load on building end walls is transferred through roof purlins to braced bays and carried to the foundations through diagonal bracing.
- The latest software that is used for design is STAAD 2006/2007.
The frame data is assembled based on number of frame members, number of joints, number of degrees of freedom, the conditions of restraint and the elastic properties of the members. Based on this, the data is stored and member section properties are computed. The overall joint stiffness matrix is obtained based on the above frame data by summation of individual stiffness matrices considering all possible displacements. The load vector is then generated based on the loading data and the unknown displacements are obtained by inverting the overall joint stiffness matrix and multiplying with the load vector.
