Abstract:
In this research was to study ways to connect the trusses by simulating analytical model representing with Finite Element Method by using the computer program Solidwork 2013. Three models were studied to connect the trusses The first model is the link by welding the second model is linked by bolts and model the third link by bolts and welding . It was the end of the installation of one of the parties and to shed load axial strain amount (30KN). Used Pin / bolt Check feature and advantage Weld Check plot to learn the proper diameter bolt which (M20*2.5) and the thickness of welding required (10mm). It was calculated stresses and displacements of the three models and compare them turned out to be less stress and displacement when the method of connecting trusses by welding (20MP, 3.62*10-2mm) and the highest value when linked by bolts (293MP, 4.91*10-2mm) either in the case of connecting bolt and welding the values (187MP, 4.04 * 10-2mm). Note that in addition to the welding area connectivity bolts led to lower stress on linking the region as well as to increase the force of Friction bolts, leading to an increase in the strength of the installation area connectivity. It was also a study represented the welding area as ((Beam using weldment-Fillet Bead feature and calculate the axial and bending as affected by the presence of the bolts holes where the value (11.4MP) when he was linked by welding only either when it became linked welding stresses Axial and bending to (20.2MP). In the end determine how either of them would be the best of the link to be performed? What distinguishes the metal structures are easily jaw and installation when needed and this happens only when the installation and bolts increased value by bolts and screws so that if used welding facility metal and you know that you will need to move you know a big mistake because you need to break the iron, but with nails, screws may just disassemble and move the metal bridges and columns to the new place after its processing rules and the composition. But if you will commends the permanent establishment and you know it welding course is considered stronger than the bolts in strength and assume moments so that makes moments and forces acting pass from a member to another member like a member of one of these is an advantage welding. It is determined best as if it intended to transfer mineral facility must be used screws and nails in all joints but if the facility will be built to get lost and transported only a matter of constructional design so if you see a clip requires a lot number of the screws is better done welding to ensure no perforation member of bolts are many holes and that lead to a weakening of the entire user interfaces in the area.
