A w14x120, W14x109, and a W16X100 are being considered as sections for the steel column with a length of 9 meters. The column is pinned at the upper end and fixed at the lower end. Use A36 steel. Fy 248 MPa. Use K(pinned) 1.0 and K(pinned-fixed) 0.7. If the total axial demand is 3500 kN, which among the sections is the most efficient?

Question: Given: A W14X109 column (A992 steel) requires a base plate (A36 steel) design. Assume the base plate will be on the full area of concrete support. The dead load compression in the column is 320 kips and the live load compression in the column is 600 kips. The concrete support under the base plate has a 28-day strength of fc 5 ksi.

Question: The fixed - fixed column W14x109 member shown below. The column is bracedagainst movement in the X-direction at 14'-0" (See Section A-A). Check to see ifmember is adequate for axial and bending.

Problem 1. Determine if the section W14x109 (A992) is adequate for beam-column interaction (LRFD) for a 15 ft long simply supported column with bracing at both supports (i.e. Lb=15 ft). Note the moments are in the perpendicular direction with X …

Problem 4 A W14x109 steel column addition to PAIS needs to be designed by the students on CE424/524 so the anchor bolts can resist a forecasted hurricane projected to come to town in the near term. The column carries an axial load of 320 kips …

Question: @ 13'0 W14x109 Problem 1: The typical exterior moment frame of a three-bay steel building is shown to the right. The trib- utary weight of the roof is 875 kip, and the tributary weights of the floors are each 1200 kip. The beams are assumed to be rigid relative to the columns, which bend about their strong axes.

The sections for columns and beams of the steel frame shown are W14x109 and W27x146 respectively and made up of A36 steel. If column AB is bent about its weak axis, determine the adequacy of its section due to loads listed below. Use ASD and load combinations for …

Use A36 steel for the base plate, assume a concrete compressive strength of 4000 psi, and a W14x109 column size (d=14.3 in, b=14.6 in). The concrete support is a square Question: Problem 1 Design a steel baseplate (i.e., provide plan dimensions and thickness) with adequate capacity to resist unfactored dead and live axial loads for each case ...
