This paper analyses several factors influencing loading properties of glass monolayer plate, such as connection manners,connection shapes,describes problems of concentrated stress of hole s edge of point support glass in glass buildings,especially the influence of concentrated stress of hole s edge and distance from center .

Effection of support point on grinding quality of outer raceway of double row angular contact ball bearing;

Design of point-supported plane grid structure with light roof;

With the increase of the need to long span and big room, the application of point-supported grid frame gets more abroad.

Glass architecture with point supporting system has undergonea great development in recent years.

The distinguishing features of the paper are selection of oblique strip and loading transmission, negative yielding line in irregular slab with simple supports, point support and shear split of slab.
