In-situ concrete hollow floor is our country in recent years, the emergence of a new type of floor system, saving material and reduce the structural weight, applicable span the obvious noise insulation effect and the overall economic efficiency of advantages. In 2004, the technology by the Ministry of Construction as the popularization and application of technology. Situ concrete hollow floor structure of technical regulations \is not perfect. Through theoretical analysis and experimental research, Hollow board of horizontal loads. Force performance of the column structure, and so on behalf of the calculation of the beam width and its influencing factors. This paper is divided into five parts. On the research background, the hollow slab - column structure research status and the hollow floor frequently used internal force analysis method and PKPM design using equivalent frame method are described in detail. 2, using the concept of \on behalf of the beam width coefficient comparison, the equivalent beam width coefficient formula. 3, numerical analysis method of cloth tube direction on behalf of the beam width coefficient; analysis on the geometric parameters of the column section height, thickness, rib width, the diameter of the core barrel, solid area the width of the coefficient on behalf of the beam width law, asked the same geometric parameters conditions, hollow board - equivalent beam width of the column structure than the structure of large solid plate column. 4, via hollow slab - column structure, scale 1/3 scale model test under lateral loads, hollow slab - column structure force performance study; through low cyclic horizontal load test load of the structure - displacement hysteresis back and skeleton curves on the ductility of the structure; floor Reinforced Concrete strain analysis confirmed that the the floor the sectional bending stress along the plate width range distribution is uneven, that there is \; through the comparison of the theoretical value of the coefficient of elastic stage and on behalf of the beam width, test value, and GB50010-2002 specification, validation elastic stage on behalf of the beam width coefficient formula proposed specification values ??safe side. 5, on the basis of summing up the work of this study, the hollow slab - column structure has yet to study the problem further outlook.
