Question

CIVT 3701K 09/19/2019 Structural Analysis ymmetrical building has a total area of 1600 ft?. For this structure, ave been placed at every 10 ft interval in either direction a. Sketch and label the system (5 Points) Calculate the Tributary area for the column placed on the third row and third column (9 Points) Calculate the influential area for the comer most column placed on the fourth row (6 Points)

Answer 1

14) Single storey Symmetric building Total area = 1600 f² Each dimension of building - 11600 = 40 ft. placed at loft interval .. BBU loft < 10x4=40ft - b) Tributary area for column placed in 3rd row & third column The column is highlited in the figure as column Tributary area => 10x10 = 100 ft2 soft 54

c) Influential area column placed on at is marked as for colner most fourth row column ③ gure Aonferential = K L Atributary Kil= element live load factors Type of element Interior column I ke | 4 Exteriol column coitht out cantilever slabs Edge column with Cantilever slabs Coner column without cantilever slabs 2 At o f 5x10 = 50f2 Given column is exteriof column without cantilever slabs - Ku = 4 . Agnfuent= 4x50 = 200 f2
