DEPARTMENT OF CIVIL ENGINEERING, IIT DELHI I SEMESTER 2021-2022 ASSIGNMENT # 2 Assigned on: 08.09.2021 CVL 441 STRUCTURAL DESIGN Submission by: 26.09.2021 Maximum Marks = 6 (out of 100 marks) Course Coordinator: Dr. Alok Madan A single story glazed building (with glass cladding) is L shaped in plan as shown in Figure 1 and consists of a flat slab constructed monolithically with rectangular columns that are all identical with their lateral stiffness in x direction twice of that in the y direction. If the vertical gravity loads (dead and live loads) are uniformly distributed over the floor area, (a) Locate the center of mass (CM) by determining the coordinates; (b) Determine the lateral load shared by (i) column A and (ii) column H under an earthquake load (EL) of 100 kN acting at the floor level at an angle of 30o to the x axis; (c) Locate the center of rigidity (C.R.) of the building by determining the coordinates; and (d) Determine the lateral load shared by (i) column A and (ii) column E due to wind loading induced by a uniform wind pressure of 2.0 kN/m2 acting in the x direction on the windward y-z face of the building. Assume that  the slab acts as a rigid floor diaphragm and entire seismic weight of the single-story building is concentrated in the floor slab.  the wind load acting at any floor level can be obtained by considering a tributary area equal to half of the total projected areas of floor above and below. Hint: The earthquake load acts through the center of mass of the floor slab. *Note: Refer to Background Theory on Rigid Body Mechanics (Statics) and the Solved Example appended / published immediately after the current page / slide / file for detailed guidelines for deriving the Solution to the Assignment Question y A
