Pinned pinned effective length
WebbTHE EFFECTIVE length concept for column design in unbraced frames has been incorporated in the AISC Specification since 1961. In simplified terms the concept is … Webb410 views 2 years ago Here's where we do a lot of math to determine the slenderness ratio and effective length of an ideal column pinned at both the top and the bottom.

WebbThe effective length is the length between points of inflection (points of zero bending moment) on the buckled shape. Thus an actual column of length l with certain rotational … Webb6 okt. 2004 · Table A4 has a K value of 0.7 + 2k for fixed-pinned-pinned. "k" in this formula is the ratio of short column length to long column length (i.e. k < 1). If this is a pinned-pinned-pinned condition, then K = 0.7 + 0.3k. In each case, L is the distance between the end and knee brace. Reply To This Thread
WebbTherefore for a column with two fixed ends, we use an effective length of: L e = ½ L Finally lets consider a column with one fixed end and one pinned end. Again, the pinned end is … Webb13 juli 2012 · If you build a model with pin top and btm and run the elastic critical load it will tell you k=1.0. If you run a fixed-end model it will tell you k=0.7, and some degree of rotational fixity will vary from 0.7 to 1.0. Only time I have used this is to calculate k-factors for rc columns in braced frames.
WebbPhysically, the K-factor is a factor that when multiplied by actual length of the end-restrained column (Figure 17.1a) gives the length of an equivalent pin-ended column (Figure 17.1b) whose buckling load is the same as that of the end-restrained column. It follows that effective length, KL, FIGURE 17.1: Isolated columns. c 1999 by CRC Press LLC WebbNoun.
