    The display font size is also essential for a proper display of the program window. In the Windows

    menu Startpoint to Settings, click Control Panel, and then double click Display. On the Settingstab,

    clickAdvanced, then you will find the Font Size list on the Generaltab. Small fonts (standard) should

    be selected, otherwise several items might not be completely displayed.

    Basic information about the FRP Lamellauser interface

    You will find general information about Windows user interfaces in your Windows manual or in the

    online help function of your Windows operating system.

    Title bar The uppermost line of the FRP Lamella program window shows information

    about program, data file and path.

    Menu bar The items File, Calculation, Extrasand Infoon the menu bar lead to different

    submenus. You will find a detailed list of all menu items in chapter 3.1.

    Tool bar The most frequently required functions can easily be called from the toolbar by

    clicking one of the symbols. You will find a detailed list of all tool bar symbols

    in chapter 3.2.

    Tree view The tree views in the left part of the program window enable you to call the

    1.4 Data input

    The required data is entered on several input windows shown in the upper part of the program user

    interface. The titles of the different windows are listed in the opposite tree view. They are classified

    according to the topics general information, cross-section, loads, flexural and shear strengthening.

    Every input window shows a graphic to illustrate the essential data.

    To show the different input windows click the related title in the tree view. If one heading includes

    several subordinated windows, the first window will be displayed automatically. Input windows that

    are not accessible yet are displayed in light grey.

    Use the button on the right below the picture box of each input window to display the next

    window. It is recommended to follow the sequence of the windows to make sure that no window is

    left out. The button on the left below the picture box leads to the previous input window.

    Enter the required data in the provided text boxes of each window. If necessary overwrite the

    entry 0. Text boxes with a grey font are locked and cannot be modified. Disabled text boxes

    having a dark background are not considered in the calculations.

    The key buttonin the toolbar enables you to unlock input fields having a grey font and modify the

    preselected values.

    For some items you can choose from a list of different values.

    After you have entered all required data you can start the calculation either by clicking the button

    calculation below the graphic of the input window FRP cross-section or by clicking the

    calculator symbolin the toolbar.

    Start the proofs of anchorage and shear capacity by clicking thebutton proof below the graphic

    of the corresponding input window. A click on the tick symbol in the toolbar will carry out all

    proofs successively. This function is useful after reopening an existing input data file.

    the topics general information, strengtheningand proofs.

    To show the different output windows click the related title in the tree view. If one heading

    includes several subordinated windows, the first window will be displayed automatically. Output

    windows that are not accessible yet are displayed in light grey

    The result values are displayed in text fieldshaving a light grey or coloured background. These

    values cannot be modified.

    Pay attention to the output fields highlighted in blue or red colour. They will show you if the proof

    conditions are met and if special details of construction have to be followed.

    The output windows of strains in ultimate limit stateand strains in service stateadditionally show agraphical representationof the strain distribution (s. chap. 2.14 and 2.15). You can change the

    scale by clicking the picture.

    The performed calculations can be printed on any printer installed under Windows operating systems.

    You can modify the content of the heading line in the menu Extras >> company letterhead. It is

    possible to print each page individually.

    2.2 Input window code

    In this window you can choose the underlying code and guideline for the design. Additionally you

    determine the material properties as well as the unit measurement for the input and output. These

    adjustments are saved on your computer so that they are reloaded at the next start of the software.

    Choose the code according to which standard you want to perform the design of the

    strengthening measure simply by clicking the related option button (not every version offers the

    possibility to choose the code).

    Afterwards choose the guidelineon which the design of FRP strengthening shall base. But only

    certain combinations of concrete design code and FRP guideline are possible.
