• Floating point division by zero

    On performing a modal analysis (eigenfrequencies, eigenvalues) in PowerFrame, following error appears: Floating point  division by zero Solution Mostlikely the correlation factor φ, for taking into account modal masses, is at 0 for all load groups: Go the Loads window In the palette, click on . Fill out the φ…

  • Error: De lastencombinaties ontbreken

    Bij het berekenen van de wapening , krijg je de foutmelding: Om de wapening te berekenen, heeft Diamonds de volgende belastingscombinaties nodig: UGT FC – Uiterste grenstoestand Fundamentele combinatie BGT QP – Bruikbaarheidsgrenstoetand Quasi-permanente combinatie BGT ZC – Bruikbaarheidsgrenstoestand Zeldzame combinatie Als één van bovenstaande ontbreekt, kan de wapening niet…

  • How to modify the image resolution

    The images in the RTF report are pixelated after printing. The resolution of the printed images can be too low. However, you can set the resolution higher: Close Diamonds. Go to My Documents > Diamonds > {current version} Open Diamonds.ini with Notepad Press CTRL + F and search for TGENERALPREFERENCES_PREF. Scroll…

  • Diamonds crashes on making load combinations

    When Diamonds crashes on creating the load combinations, it probably means that you have to many load cases. For every load case, the favourable and unfavourable effect must be considerd, as well as the interaction with the other loads. Suppose that you have 17 different live loads, then Diamonds needs…

  • How to interpret the reinforcement of a beam or column

    General Ay – Representation of the longitudinal reinforcement parallel to the local axis y’. Therefore, in most cases, this is the lower and upper reinforcement. Az – Representation of the longitudinal reinforcement parallel to the local axis z’. Therefore, in most cases, the lateral reinforcement. Awz – Representation of the…

  • What is the meaning of the little guys in the loads window

    With the parameter “always together” you can force the program to consider the loads of a load type always as one undividable load. Otherwise, ConCrete will automatically load some spans with the favourable load factor and other with the unfavourable load factor to obtain the most damaging load situation. It…

  • How to interpret the elastic results graph

    In the combinations ULS and SLS, load groups are multiplied with a safety factors for unfavourable and favourable effect. This results in minimum and maximum results for shear force, bending moments and deflections. The solid line is for the maximum result, the dashed line is for the minimum result.

  • How to interpret the deflection graph

    There a 4 types of lines on the deflection graph: The black lines are the elastic deflections: A black dashed line for the minimum deflection A black solid line for the maximum deflection The red lines are the cracked deflections: A red dashed line for the minimum deflection A red…

  • Please check the resistance of the horizontal parts of the stirrups

    On transferring a beam from Diamonds to ConCrete Plus, the message appears [NL]: Controleer of de horizontale benen in staat zijn om de krachtswerking te weerstaan [FR]: Vérifier la résistance des barres horizontales des cadres. Solution In Diamonds, beams can be loaded both in and out of the plane. This…
