  • Glass Load Resistance Report according to ASTM E 1300-09

    glass-load-resistance-report

    OVERVIEW:

    Saudi American Glass performs all required calculations to design window glass according to ASTM E 1300-09 using Windows Glass Design 5. This applies to vertical and sloped (overhead) glazing in buildings exposed to a uniform lateral load. Our calculation covers monolithic, laminated, or or insulating glass of rectangular shape with simple supports along two, three, or four edges.

    The specified design loads may consist of wind load, snow load, and self-weight with a total combined magnitude of less than or equal to 10 kPa. However this calculation does not apply to other applications such as balustrades, glass floor panels and point-supported structural glass members. For such service, we have our finite element analysis which can perform more complicated calculations.

  • Finite Element Analysis of Glass

    finite-element-analysis

    OVERVIEW:

    We are capable and equipped with a finite element program specially developed to perform static and dynamic calculations of glass structures. We can calculate any shape of system including laminated glass, point fixings, balustrade clips and all this for insulated glass. Any bearing and loading situations are possible, considering load cases or dynamically calculated impacts for the use of glass as fall protection.

    Variety of Calculation Possibilities:

    • automated mesh generation for straight or curved borders by the input of corner points. The element size is preset, but may also be changed manually to increase the accuracy of the calculation.
    • with this, any system shape including cut-offs or holes are possible
    • all subsequent calculations can be made linear or geometrically non-linear (large deformations).
    • any pane structure (e. g. of laminated safety glass) considering the stiffness of the compound material by input of the layer order
    • consideration of pre-defined bearing designs for the plate edges as well as for any point bearing with the corresponding spring rigidities
    • fully automated installation of point fixings
    • countersunk or disk fixings (own elements) with the stiffness of the circular plate layer and the bush by means of elasticity-module and thickness specifications
    • balustrade clips with circular or angular shape (usable as glass shoes)
    • downholders with circular or angular shape
    • bonded fixing without generation of holes
    • point fixings with covering glass panels
    • specification of the bearing stiffness (sub-construction or type of the point fixings)
    • optional use of springs or tie bars at the point fixing
    • the properties of the point fixings can be stored in a database
    • point supported insulating glass units
    • spacers in insulation glass (e.g. unsupported borders)
    • elastic edge or line supports including contact conditions
    • elastic beams acting at the borders
    • elastic base calculations
    • any positioning of local springs with translation and rotation degrees
    • effect from temperature differences given for each layer
    • face loads, line loads, water pressure
    • dead weight (indication by the direction of the gravity vector)
    • any point loads which are automatically distributed over the given area
    • calculation of insulation glass under consideration of the gas pressure laws in the intermediate pane space (gap) under any load (climate loads like pressure differences, thermal expansion of the gas, external loads, pendulum impact,…)
    • calculation of load cases with any combinations of loads and related safety factor
    • automated load case generation and design proof
    • additional protocol with load case results and resistance check
    • open protocol format to be used in any word processing program
    • point fixings or the panes inside the insulation glass can be calculated with contact algorithms
    • applying loads at fixings
    • dynamical calculation of the pendulum impact for single-layer glass, laminated and insulation glass of any design
    • the drop height of the pendulum and the impact point can be freely chosen
    • linear or non-linear approaches for single glass layers, laminated safety glass and also for insulating glass units
    • output of curve diagrams for forces, deformations and stresses during the impact period for any predefined position
    • stresses across the plate thickness and layer order at any point
    • display of the pendulum impact in slow-motion
    • output of all stress components
    • vector-plot of the principal stresses
    • colored display of deformations

  • Blast Resistance Reports

    blast-resistance-reports

    OVERVIEW:

    SAG provides an accurate analytical model of window response to the effects of an explosion. Our software accepts user input of window system properties and explosion characteristics, and then calculates the performance of the window system when subjected to the defined blast loads.

    Calculation Possibilities:

    • Quickly model a variety of glazing systems and predict glass fragment hazard
    • Calculate and display time-history plots of loading, displacement, velocity, acceleration, and reactions
    • Model a wide variety of glazing systems ranging from simple, monolithic systems to complex insulating glass units (IGU’s), including multi-layered and ballistic-resistant materials
    • Simultaneously evaluate multiple window openings
    • Automatically determine glazing capacity
    • Generate Pressure-Impulse curves
