Design and Analysis of Large Rolling Shutter - A Review

In this paper we are going to discuss about the construction and analysis of large rolling shutter. The shutter is made up of plurality of slats inter-connected with each other. The shutter provides safety against weather conditions and burglary. The configuration of slat must be such that the rain water must not accumulate between two consecutive slats. The shutter curtain travels in the guide channels to open and close, provided at the either side of the shutter. The pulley system or direct mechanical mechanism can be installed for the opening and closing of shutter. If the size of the shutter is big then a motor can also be installed for the opening and closing of shutter. The wind load is to be considered for the designing of the shutter curtain since the load is mainly due to wind velocity. The curtain must with stand the high velocity wind. The nonlinear analysis of the shutter curtain is carried out because of the thin structure.
