The beam of building structure (Fig. 3a) is made of mild steel I-section beam with 80mm deep and 60mm wide as shown in Fig. 36. The beam is bolted (simply supported) onto the girder on both side over a span of 1.0 m. The loading from deck is expected to transfer onto the beam as the form of uniform distributed load, w. The material is to be treated as elastic-perfectly plastic, with yield strength of 240 MPa, and elasticity modulus...
Question 2 I (a) Using a 459 strain gauge rosette placed on a mild steel structure, the following strains were established from the measurements taken:£x = 75x10", Eyy =-115x10-6 = 210 10-6 and Yxy yy (i) Determine the corresponding normal stresses Ox and and shear stress txy. For mild steel, use Young's modulus E= 205 GPa , Poisson's ratio v=0.3 and shear modulus G = 78.8 GPa. [6 marks] (ii) Using the values obtained in (i), determine the principal stresses...
