  • The design of a power transmission shaft which has the limited life under cumulative damage and various mean loads was made in consideration of shaft stiffness and shape determination. All procedures were programmed so that one can see the result by connecting to graphic terminal. The diameters of designed shaft are in good agreement with those of a commercial shaft which is manufactured according to the imported design drawing sheets.

  • The trends in building construction these days are moving towards having better work space and greater suitability for the use of information technology, Therefore people can work in a more relaxed, delightful and pleasant environment. So accidents like fire could cause the mass destruction of human beings. In this paper, we estimated the escape time from a building and simulated the study results on computer to see how safe it would be in a real situation.
