Flexible support system of point supported glass curtain wall is a new system on which the civil engineers have not much experience. This situation limits engineer design for this system. In combination with the experience of design for point supported glass curtain wall, the authors discuss some problems met on the design, but not solved, which can give reference to engineers.
