Safety analysis of connection strength of the hoistway and the building

There have a great number of existing residential buildings in china that do not have elevators installed, which plagued the lives of aged residents living in for apparent inconvenience. The installation of elevators in these buildings comes into being under this circumstances. In this paper, the hoistway and the building were considered as a whole, and a three-span single safety under the coupling of safety clamp-rail- building was established. The deformation of the guide rail and the force of the supporting point were calculated by three-span guide rail model, when the safety clamp was in motion. It provided a theoretical basis for the calculation of the force and the safety analysis of the elevator steel structure hoistway.
