'Cmx' is the coefficient applied to the X-axis (major axis) bending term in the interaction equation (H1-1) and is dependent upon column curvature caused by applied moments.

SLENDERNESS RATIO K FACTOR IN AISC 14TH EDITION CODE

Very closely approximate the solutions for 'Kx' and 'Ky' obtained using the AISC Code Alignment Charts.) Then, these calculated valuesĬan be input under the member design parameters on the main page. Input data to the right of the main page in each of the calculation worksheets. The values of 'Cb', 'Cmx', 'Cmy', 'Kx, and 'Ky' may be calculated (if applicable) by accessing the additional.When a stiffened element (web) of a member subjected to axial compression is classified as a "slender"Įlement (exceeding non-compact limits) based on local buckling criteria, then the calculator complies with When the values of either 'Lx', 'Ly', or 'Lb' are input = 0' (or actually For the case of combined axial compression with bending, if the calculated value of fa >=F'e (which is notĪllowed) then a warning (error!) message will appear.However, this calculator DOES NOT consider or deem a particular member as"inadequate" based on the slenderness ratio of 200 being exceeded. If an axially loaded compression member has a value of the maximum slenderness ratio K*L*12/r >200,.Value of 1.333 may be used for load combinations which include wind or seismic loads. It is used and appears ONLY in the stress ratio calculation. This calculator utilizes an "Allowable Stress Increase Factor" (ASIF) which is a multiplier of any of theĬalculated allowable stresses Fa, Fbx, and Fby and also the Euler column buckling stresses F'ex and F'ey.In this calculator for members subjected to known loadings consisting of axial load (compression or tension)Īnd/or uniaxial or biaxial bending, both the actual and allowable stress are computed, with the final resultīeing a computed "stress ratio" of actual stress/allowable stress.

SLENDERNESS RATIO K FACTOR IN AISC 14TH EDITION MANUAL

This calculator follows the procedures and guidelines of the AISC 9th Edition Allowable Stress (ASD) Manual.Merely move the mouse pointer to the desired cell to view the contents of that particular "comment box".) (Note: presence of a “comment box” is denoted by a “red triangle” in the upper right-hand corner of a cell. This calculator contains numerous “comment boxes” which contain a wide variety of information including explanations of input or output items, equations used, data tables, etc.The slenderness ratio of reinforced concrete columns can be computed according to the procedures and specifications of applicable codes such as ACI 318-19 and IS 456. So, the slenderness effect should be taken into consideration during the design process. If the slenderness ratio of a column is high, it will collapse under a smaller compression load in contrast to a short column with the same cross-sectional dimensions. The design of the former is controlled by column dimension and material strength whereas the design of the latter is governed by column slenderness.Ī column is said to be slender if its cross-sectional dimensions are small compared to its length. The slenderness ratio differentiates short column from long or slender column. The slenderness ratio is calculated by dividing the column length by its radius of gyration. It assesses the ability of the reinforced concrete column to resist buckling pressure. The slenderness ratio of a reinforced concrete (RC) column is the ratio between the length of the column, its lateral dimensions, and end fixity.
