The beam has a rectangular cross section width b and height t The material of the beam is steel The two objectives are the fabrication cost of the beam and the deflection of the end of the beam under the applied load P The load P is fixed at 6 lbs and the distance L is fixed at 14 in The design variables are Sep 13 A torsion will develop in the supporting beam how small/large depends on relative stiffnesses loads and resulting deformations/twists so if welding it is the only option then its a matter of designing the supporting beam for the present using the relevant combined actions checks in your local codes Apr 14 Today we will learn about electron beam welding principle working equipment’s application advantages and disadvantages with its diagram Electron beam welding is a liquid state welding process Liquid state welding are those welding processes in which the metal to metal joint form in liquid or molten state In summary the shear stress on the welds has the constraint < = The normal stress on the welds cannot exceed 30 psi The normal stress is The buckling load capacity in the vertical direction must exceed the applied load of 6 lbs The welding head travels along the joint and welds it by single wire submerged arc Clamps are released and web is conveyed to the tacking fixture Welding equipment consists of welding head with flux hopper travel carriage controls and a 1 Amp power source H Beams also called I Beams or girders are more expensive and more difficult to transport in longer lengths You can weld to H beams together end to end to avoid the difficulties of shipping a 50 foot beam for example A good weld will provide as much or more strength as non welded segments beam Weld Design for shear 1 Find properties of the built up section I Q with respect to the area above the upper flange of the channels 2 Compute fv = V Q/ I b in which b = tp 2 bf of channel 3 Design the weld for the shear force fv A bflange Then fv should be combined with fb as discussed above The ready template of the design estimate sheet makes it easier to work on The user friendly feature of the spreadsheet along with automated functions reduces the unnecessary hard work Keyword for this page beam splice welded connection design beam splice design example steel beam to column connection design example forcing beams and columns as well as welding and tolerance considerations beams Let’s start with beams Floor systems roofing or other ob structions may limit access and prevent welding to both flanges of a beam This limited access combined with the desire to eliminate overhead welding usually leads to built up shapes that are singly

For the example given above the equation would be q = VA1 Y y1 / Itotal 4 General Procedures It is often unnecessary and uneconomical to reinforce a beam along its entire length The first step is to determine the shear and moment diagrams in order to locate the regions requiring reinforcement The following example uses a W12x26 twenty feetCE Design of Steel Structures – Prof Dr A Varma Example 2 2 Design a simply supported beam subjected to uniformly distributed dead load of lbs/ft and a uniformly distributed live load of lbs/ft The dead load does not include the self weight of the beam • Step I Calculate the factored design loads without self weight the right Beams that overhang a support at one end are shown at the right The reactions at the supports may be of different magnitudes and you’ll need to keep them organized as they may be used or accumulated for a beam or post load later in your design analysis The left reaction is called R1 the right reaction is R2 This 10 ft Linde Side Beam and Carriage Welding System is ready to be rebuilt with a welding process of your choice This side beam uses the very popular and heavy duty OM 48 Linde carriage Equipped with cam follower bearings and large cast wheels this carriage is tough enough to hold even the heaviest of welding processes CE Design of Steel Structures – Prof Dr A Varma Example 6 2 Design a double angle tension member and connection system to carry a factored load of kips Solution Step I Assume material properties Assume 36 ksi steel for designing the member and the gusset plates Assume E70XX electrode for the fillet welds Step II DESIGN EXAMPLES Comparative Shrinkage of Sawn Timber and Glulam Beams / Simple Beam Design / Upside Down Beam Analysis / Tension face Notch / Compression face Notch / Sloped End Cut / Beam Stability Effective Length Method / Beam Stability Equivalent Moment Method / Cantilever Beam Stability Equivalent This course will feature a bolt design example utilizing AWC& 39 s National Design Specification® NDS® for WdC t tiWood Construction T i ill i l d ti d iTopics will include connection design philosophy and behavior an overview of NDS provisions related to bolt design including Appendix E for local stresses in fastener groups and a REES Module 6 Railway Alignment Design and Geometry 14 Design Grade for Railways • Ideal maximum for railway grade • Trains can roll safely down 0 3% grade without wasting energy on brakes • < 0 1% for tracks for extensive storage • Railway vertical curves – old formula L = D / RThe welding head travels along the joint and welds it by single wire submerged arc Clamps are released and web is conveyed to the tacking fixture Welding equipment consists of welding head with flux hopper travel carriage controls and a 1 Amp power source A flux recovery system is provided to dispense and recover welding flux
