1. For a column-cantilever beam shown below, answer to following questions. Note: fcx = 24 MPa, fy = 400 MPa, normal-weight concrete, wa= 20 kN/m (including self- weight), wi= 40 kN/m a) (5 pt.) Determine the required steel area As if the cantilever beam is to be a tension controlled section (Tip: Try 145 mm as a first trial value of a in the iterative method) b) (5 pt.) Check if the provided steel ratio satisfies the provision for steel ratio in KCI code. c) (5 pt.) Check if the embedment length of flexural bars in the cantilever beam satisfies the provision for development length in KCI code. You need to use the basic equation when you calculate the development length of the cantilever beam. d) (5 pt.) Check if the embedment length of flexural bars in the cantilever beam satisfies the provision for development length in KCI code. You need to use the simple equation when you calculate the development length of the cantilever beam. e) (5 pt.) Check if the embedment length of flexural bars past the column face satisfies the provision for development length in KCI code. You need to use the simple equation when you calculate the development length. Note: strength of column concrete fet = 35 MPa 40 mm 40 mm + + 14 2-D35 51 mm 76 mm 610 mm 540 nm 230 mm | 0.51 m 2.5 m 460 mm * 1.
