Consider a two-story building modeled as a 2-DOF system. If the first floor has a stiffness of 30000 N/m and the second floor 25000 N/m, calculate the effective stiffness and explain how this affects the overall building's dynamic response.
💡 Hint: Focus on how modifications in stiffness affect natural frequencies.
Analyze the effects of torsional coupling in an asymmetric building modeled as a 2-DOF system under earthquake loading. What are the implications for design?
💡 Hint: Think about how mass distribution influences torsion.
