Project 2_Analyze and Design the RC office building as per IS standard code in TEKLA STRUCTURAL DESIGNER
AIM-- Develop general arrangement for the RC office building. Analyze and design the building as per IS standard code in TEKLA STRUCTURAL DESIGNER. Refer the attached plan and elevation. The building to be designed for dead, live, wind and seismic loading.
Report of each member to be generated and extract drawings for structural plans, beam reinforcement details from the software

FINISHES --
THICKNESS =50MM

BRICK WALL WIT CEMENT PLASTER =
THICKNESS OUTER WALL = 230 MM
DEAD LOD DUE TO BRICK WAALL 230 MM= 0.23*(3.7-0.6)*18=12.83 KN/M
THICKNESS INNER WALL = 150 MM
DEAD LOAD DUE TO BRICK WALL INNER 150 MM= 0.15*(3.7-0.5)*18 = 8.37 KN/M
