Glass Load Calculator. The table has been based on maximum glass area of 3.4m2. This calculator will help you to estimate the approximate weight of the various glass shapes (circle, square, rectangle, triangle and semi-circle) based on the glass type, thickness and the other known values. SJ Mepla - Software for Structural Glass Design SJ MEPLA is a finite element program specially developed to perform static and dynamic calculations of glass structures. Table 5 – Thickness of glass infill panels for barriers Discussion—For loads having durations other than 3 s or 30 days, refer to Table X6.1. IGDB Version 30.0 Values are calculated using the LBNL Window 6.3 program and represent the 'center-of-glass' region of the glazing. >> The glass type and thickness, the distance between supporting brackets, and other factors will influence whether your glass can meet your weight limits. If you are ordering glass for use as a shelf, use this tool to make sure that it will support the weight of the items you want to put on it. The majority of loads which glass has to withstand are caused by bending and probably the most important external factor in specifying a suitable glass thickness is the design wind load. that laminated glass is suitable for barriers where the glass is used fully framed. The main purpose of the glass calculator is to assist designers in the proper selection of glass thickness to resist a specified load or load condition. The thicknesses may need to be increased depending on the size of the panes and on other possible load requirements. A related consideration is the deflection of glass-supporting frame members, typically limited to L/175 (where L is the span length), to avoid excessive stress on the glass that could lead to breakage. A third consideration is providing for movement due to differential thermal expansion or contraction between aluminum and glass. Calculate for toughened, laminated and annealed glassed … Load Resistance calculations based on the basic method in Standard Practice ASTM E1300-16 Rectangular single glazed monolithic annealed glass and laminated annealed glass fabricated with PVB interlayer, simply supported on 4, 3, 2, and 1 side(s) Wind load computation procedures are divided into two sections namely: wind loads for main wind force resisting systems and wind loads on components and cladding. non-factored load (NFL), n—three second duration uniform load associated with a probability of breakage less than or equal to 8 lites per 1 000 for monolithic annealed glass as determined from the figures in Annex A1. This low-maintenance frameless glass balustrade system uses nearly eight metres of SG12 21.5mm toughened laminated glass. The need for cleaning is reduced further with the application of BalcoNano self-cleaning glass coating – an ideal choice for an outdoor balustrade. Calculation Procedure for Design Wind Load on Curtain Walls The design wind load can be found according to ASCE 7-10 (minimum design loads for buildings and other structures). SAINT-GOBAIN GLASS can give general guidance on short duration wind load pressures.
