Aiming at solving the difficulty in girders being small in number for small railway bridges and the construction site being limited for erecting prefabricated girders,the soluble internal forms are recommended to realize the casting-in-place of prefabricated girders in the paper.

This paper reports an experimental study on seismic behavior of a six-story two-bay frame with precast beam and cast-in-place column,which is from a six story prototype residential building.

By combining with 8×25 m cast-in-place prestressed concrete continuous box girder bridge construction,the paper introduces the application of WDJ upside down bowl-type bracket in cast-in-place prestressed concrete continuous box girder bridge construction as the construction structure,so as to accumulate application experience for WDJ bowl-type scaffold.
