| 摘要 | A beam (20) comprising first and second flanges (23, 24), the beam (20) having a first region (28, 30) extending between the flanges (23, 24) and a second region (26) extending between the flanges. The first region (28, 30) is designed to support an applied concentrated shear load and the second region (26) is designed to support a predominantly bending load. The first region comprises a fan-shaped truss comprising a hub (36) adjacent the first flange and a plurality of struts (37) which extend substantially radially from the hub (36), and the second region (26) comprises either a truss structure which is substantially regular in the longitudinal beam direction or a shear web. The beam may, for example, be used as a floor beam for an aircraft fuselage. | ||

| 主权项 | 1. A beam comprising first and second flanges, the beam having a first region extending between the flanges and a second region extending between the flanges, the first region including a fitting configured to receive an applied concentrated shear load, and the second region being designed to support a predominantly bending load, wherein the first region comprises a fan-shaped truss comprising a hub adjacent the first flange and a plurality of struts which extend substantially radially from the hub, and wherein the hub is aligned in a vertical direction with the fitting and the second region comprises either a truss structure which is substantially regular in the longitudinal beam direction or a shear web. | ||
