The minimum spacing of bars in circular cross-section is does not satisfy. Create an Account – Increase your productivity, customize your experience, and engage in information you care about. The value sets minimum value of compression strength of concrete.
This factor should be used for calculation if tensile reinforcement in reinforcement value e t is lesser than 0. Value of minimum percentage loaded from edit box.
There are three possibilities for calculation ratio of reinforcement in biaxial bending calculation:. Maximum axial resistance without bending moments. The comparison of the bending moments with and without capping for standard support and for column support is done in the following table.
For automatic calculation, factor b d is calculated in each sections of the compression column, it means that in each section at length of compression member the different value can be taking into account. Open Thema mit Navigation. This is code independently check. This setting is used for iterative calculation in concrete.
Design strength of the structure is calculated multiplying the nominal strength by a strength reduction factor f. Else if this check box is ON, then iterative calculation for strength reduction factor will be used for design reinforcement to beam “8.
The value sets maximum value of compression strength of concrete. The value from edit box value s t,max is used for calculation number of cuts of shear reinforcement independently if check box is ON or OFF. For nonprestressed flexural members and nonprestressed members with factored axial compressive load less than 0.
These values should be calculated before design of reinforcement, but before design we do not know area of reinforcement. User may define default settings separately for beams, columns and beam slabs members, in each of three folders. The Building Official and a team of construction management specialists also oversee major city capital projects including those buildings authorized for funding by the voter approved “Measure D” of This value is maximal available yield strength of the reinforcement used for the design of shear reinforcement.
It is also possible to define sway type here. Use different value Alpha or different method. In this case, the result will not be presented and user has to make some changes in calculated structures or decrease precision of iteration see chapter “4.
Concrete setup for 1D member
In 2D concrete setup dialog, different folders will be displayed. This setting is used for number of bars in circular column. The Engineering Division deals with development on private property and connections to city infrastructure. The comparison of results for different reinforcement type and different xci are of reinforcement for columns with different size number of reinforcement is in table below.
After switching ON this check box Advanced setting, there are much more parameters for setting calculation of the columns.
The calculation moment of inertia of reinforcement depends on type of method and shape of concrete cross-section acci. It 351-05 possible to define minimal concrete cover, set default values for member design, such as reinforcement diameters, and materials both independent for main reinforcement and stirrups. Value x is user defined value and default is for US unit format and 1,4 for metric format.
This edit box is used for inputting user input of factor b d. Design defaults for Beams are shown on the first picture of this chapter. If this check box is ON, then the results are calculated and presented only at the ends of the member and in user defined sections.
The Building Division Public Works Department interprets the Building Code by overseeing the plan check and inspection process for all construction requiring a Building Permit. Code defines maximum of the values of fy and fytused in design calculations, shall not exceed MPa, except for prestressing steel and for spiral transverse reinforcement in If this check box is ON, then centre-centre spacing between bars is checked.
According to the Code, concrete stress of 0. If clear spacing of bars is lesser than minimum spacing then design of longitudinal reinforcement finishes with If clear spacing of bars is lesser than minimum spacing then design of longitudinal reinforcement finishes with the following warnings.
By selecting this possibility, program will enable edit boxes for concrete cover, both for upper and lower surface, and user defines his own value to afi used.
The initial value of diameter for calculation is loaded from concrete setup, item Design default or from concrete member data. If this centre-centre spacing of bars is bigger than maximum spacing then design of longitudinal reinforcement finishes with the following warnings. The diameter of bars in each iteration step aaci calculated and it is rounded up to integer number.
Avi factor depends on the strain in tensile reinforcement, but this strain is unknown before design reinforcement. This item prescribes maximal allowed centre to centre bars spacing between longitudinal bars based 31-505 the chapter For delta area of reinforcement — the diameter of bar is calculated from input value of delta area.
Generally detailing provisions are split to adi provisions for beams and columns. The value delta area represents increasing area of one bar of reinforcement in each iteration step.
It is active only, if item Delta area of reinforcement is selected from combo box Area of reinforcement type. This coefficient reduces concrete compression strength. Design of longitudinal reinforcement for beams and beam as slab. Please, check the concrete setup and user should:.
