- When the ratio of the moment M to axial load P is greater than L/6, the resultant of the compressive bearing pressure which acts at a distance Y from one side, is given by
- As per IS: 800, in the plastic design, which of the following pairs are correctly matched? Working Loads Load factor (i) Dead load 1.7 (ii) Dead Load + imposed load 1.7 (iii) Dead load + load due to wind or 1.3 seismic forces (iv) Dead load + imposed load + load 1.7 due to wind or seismic forces Of these statements
- In a gusseted base, when the end of the column is machined for complete bearing on the base plate, then the axial load is assumed to be transferred to base plate
