With the button \"\" you can design elements in reinforced concrete.<\/p>\n\n\n\n

1\u20222\u2022Build will try to find the optimal section within defined limits for width and height. He will also take the imposed maximum (elastic!) deflection into account.<\/p>\n\n\n\n

You must specify the concrete strength, steel grade and gross coverage. The gross cover is the distance from the outer surface of the concrete to the centre of the longitudinal reinforcement.<\/p>\n\n\n

\"\"<\/figure><\/div>\n\n\n

Once the calculation is completed, 1\u20222\u2022Build shows a cross-section containing a reinforcement proposal. This proposal takes the maximum theoretical reinforcement amount into account. It also imposes a constant distance between the stirrups. You can also impose a reinforcement configuration by double clicking the bar<\/a>. If 1\u20222\u2022Build cannot find a suitable cross-section, a warning will pop-up and a skull will be shown next to the relevant bars.<\/p>\n\n\n

\"\"<\/figure><\/div>\n\n\n

1\u20222\u2022Build can only calculate elastic deformations. But for concrete you need the cracked deformation after creep. This deformation can be a factor 3 to 5 greater than the elastic deformation. However, it is not possible to calculate the cracked deflection after creep with 1\u20222\u2022Build. Use ConCrete or Diamonds instead.<\/p>\n\n\n\n

A custom reinforcement configuration<\/h3>\n\n\n\n

You can impose a custom reinforcement configuration by double clicking the relevant bar after completing the design. In the dialog that appears, you can change the upper and lower reinforcement, the reinforcement along the sides and the stirrups by using the different tab pages.<\/p>\n\n\n

\n
\"\"<\/figure><\/div>\n\n\n

However, it is not possible to define reinforcement that doesn\u2019t meet the requirements of the calculation. In that case, 1\u20222\u2022Build will draw a cross over the cross-section indicating that the defined practical reinforcement is insufficient.<\/p>\n\n\n
