Precast segmental construction can be defined as a method of construction in which primary load carrying members are composed of individual segments post-tensioned together as shown in Fig. The first segmental concrete bridge, built in , was cast-in-place across the Lahn River in Germany and the first precast segmental concrete bridge, was built in , across the Seine River in France Walter Podolny Advantages of this type of structures are fast and versatile construction, no disruption at ground level, high controlled quality and savings in cost. Precast segments can be incorporated to variety of bridge types such as cable stay, arches, rigid frames and girder type bridges. Precast segmental construction technology have extended the practical and competitive economic span range of concrete bridges and are adaptable to almost any conceivable site conditions as well. They are also chosen for their aesthetic appeal.

As construction industrialization is springing up in our country, precast concrete frame structure,as a result,has been developing rapidly. Based on a host of articles about precast concrete frame structure system at home and abroad,it,in this paper,summarized and prospected the latest stress performance research of precast concrete frame structure and up-to-date engineering application. Further more, total assembled node and seismic behavior of precast concrete frame structure is also pointed out as what is needed to study in the future.
