SIMULATION AND STRESS ANALYSIS OF A 40-METER SPIRAL STAIRCASE
The mainobjective review of the maximum load the system steps that are each 3 meters 40 meters of floor landing is a total of "140 stairs and railings next to the stairs and landing is 13..
The total weight of 1300 kg and the system components are connected without welding with standard screws and bolts have been studied in terms of shear strength.
Step system is one meter in diameter and trapezoidal-shaped insole steps that have been fully analyzed.Load shows the overall system software:
1. weighing 60 kg load on each step or a force of 100 Nm comes in at the same time example of a person standing on the stairs and landings conditions, computer full connection to the wall, structural strength is required. (Green field)
