Alternative Shear Wall Design On Polinema AC Building Structure

This study compares the performance of four different shear wall configurations in an eight-stories building designed with a dual structural system using the Response Spectrum method, include structural period, shear force, story drift, and cost. Four shear wall configurations are planned: (1) Existing Condition with Core Wall shear walls on the right and left sides (SW0); (2) Frame Wall in an L shape around the lift and stairs (SW1); (3) Two L shapes around the lift and stairs and two I shapes on the facade (SW2); and (4) I shapes around the lift, stairs, and facade (SW3). Simulations were conducted using ETABS, considering dead loads, live loads, and earthquake loads. Cost estimate for shear walls of each alternative. The results show that Response Spectrum Method can be used for the models. Based on Structural Performance analysis Shear wall alternatives 2 (SW2) perfoms best compare to others models. For reinforcement design, the SW2 was chosen, with longitudinal reinforcement for I-Shaped as 2D16-150, and transverse reinforcement as 2D13-155. For L-Shaped, the longitudinal reinforcement is 2D16- 150, and the transverse reinforcement is 2P12-150, matching the existing shear wall reinforcement. Based on the Cost Comparation SW0 is the cheapest among other configuration however, from the structural performance perspective, SW2 & SW3 perfom much better than those in SW0.
