By combining single layer cylindrical latticed shell (SLCLS) and beam string structure, a new-style prestressed spatial structure cable supported barrel vault structure (CSBV) is formed. Taking a practical CSBV project as prototype, a scaled model with a scale of 1:15 is designed and fabricated, the static loading test is carried out. Research results indicate that the characteristics of the prototype structure can be reflected by this model test. As the load increases, the change rule of the test values of the cables' forces agree with that of theoretical values. The two outmost cables' forces are generally smaller than the other interior cables' forces. The cables' forces in the symmetrical places keep closer. For rods' forces and nodal displacements of CSBV, the test values and theoretical values both keep closer. The differences between test values and theoretical values increases with the load. The test values are larger than the theoretical values, but the change rule still matches. Compared with SLCLS in the same condition, the rods' forces and nodal displacements of the CSBV are both smaller, and the mechanic characteristics of CSBV are more efficient.Keywords: Cable supported barrel vault, Beam string structure, Cylindrical latticed shell, Rise-span ratio, Sag-span ratio, Strut number INTRODUCTIONSpatial structures with longer span have gained more popularity in recent years. New types of spatial structures appear from time to time nowadays, such as cable dome structure, beam string structure, suspend-dome structure and cable supported barrel vault structure (CSBV). CSBV is a new-style highly efficient pre-stressed spatial structure. Inspired by beam string structure [1][2][3][4][5][6][7], and based on the single layer cylindrical latticed shell (SLCLS) [8], CSBV was first proposed. It consists of struts and cables distributed at suitable positions in the single layer cylindrical latticed shell. On one hand, stiffness of the whole structure is enhanced due to the introduction of pre-stressed cables and struts, which can effectively solve the problem SLCLS out-plane stability [9]. On the other hand, both steel usage and construction difficulty are significantly reduced. Moreover, horizontal forces that the supports bear and the burden on the lower structure are significantly reduced, due to the setting of cables which could be pre-stressed. This new-style structure was first proposed and its basic mechanical properties were theoretically studied in paper [10]. Theoretical research on mechanic feature of CSBV was carried out in paper [11], the initial prestress design method was proposed. The dynamic feature of CSBV was studied in papers [12] and [13], the wind resistant design method and seismic design method were respectively proposed.Model test is one of the best methods to study mechanic feature of a new-style structure system. Directed by theoretical research results, the static loading test on a CSBV is carried out in this paper, and test details are listed below.

Abstract：A practical suspen-dome project, Changzhou Gym roof, is adopted as an example and its transient analysis based on the multi-support excitations of the earthquake wave is carried out. Compared with the single support excitation, the position and value of the maximum stress under multi-support excitations both change and the amount of elements with obvious changes is large and more than 70% of the total. Moreover, when other terms are not changed, this influence will decrease as the span decreases, but increase as the traveling wave speed decreases. The final result indicates that the influence of the earthquake wave passage effect on the structure system is negative and cannot be ignored.
