Problem 2 The Two Story Two Bay R C Frame Shown In Fig 1 Is Subjected To A Uniformly Distributed Dead Load Of 7 5 Kn M 2 (43.51 KiB) Viewed 21 times
Problem#2: The two-story two-bay R/C frame shown in Fig. 1 is subjected to a uniformly distributed dead load of 7.5 kN/m² and live load of 2 kN/m² along with the earthquake loads. Column orientations, plan and elevation views are given in Fig. 1. Columns are continuous along the height. C25 concrete (E=30,000 MPa and Poisson's ratio=0.2) is used for all members. Self-weight of the structural members can be neglected. Any structural analysis software can be utilized. Using the given information, determine the following: (a) Determine the gravity load distribution for the frame; (b) Build a numerical model of the frame; (C) Apply dead, live and earthquake loads to the frame; (d) Plot the envelope of the moment diagrams for 1.4D+1.6L and D+L+E; (e) Find the maximum beam deflections under service loads (D+L); (f) Find the lateral displacements at each story level; (g) Find the relative story displacements.
