Abstract
The invention discloses a cable and variable-section beam-arch composite structure system which comprises inhaul cables, a support rod and a variable-section upper chord beam-arch. The upper chord beam-arch comprises a single beam, a coupled beam or a multi-joggle beam, the inhaul cables are connected with the midspan of the upper chord beam-arch through the support rod, two ends of each inhaul cable are anchored at two ends of the upper chord beam-arch respectively through anchorage devices, the inhaul cables are arranged in reserved ducts and grooves of the upper chord beam-arch or gaps between the coupled beam-arch and the multi-joggle beam-arch within the range of 1/5-2/5 of the span away from supports, and the other parts of the inhaul cables are exposed. The inhaul cables can be linearly arranged along the bottom surface of the variable-section beam-arch and are only exposed in parts of the midspan range, so that attractiveness of buildings and mechanics is reflected. In addition, the composite cross section of the cable and the variable-section beam-arch is flexible and can be a single beam section, a coupled beam section or a multi-joggle beam section, and flexible arrangement of the inhaul cables is greatly facilitated.
Description
Technical field
The present invention relates to a kind of rope and non-uniform beam, arch combined structure system, main (but not exclusively) is used for fields such as building structure building roof system and bridge superstructure.
Background technology
Suo Liang, arch combined structure system are connected the plane self equilibrium systems that forms as beam or arch with high wringing by strut, not only given full play to arch form structure advantage, taken full advantage of the high-tensile of rope material, and because strut provides elastic support to arch, improved the ability that arch bears vertical load, obtained using widely.This structural system has simple, stressed clear and definite, the advantage such as form of structure is various, couple hardness with softness, and adaptive capacity is strong of system.
The beam that winds up, arch in traditional Suo Yuliang, the arch combined structure system are generally the scale cross section, and for large-span structure, the load that its deadweight produces is bigger, and its span of this military order and supporting capacity are subjected to certain limitation, and simultaneously, there is certain redundancy in the material that winds up; In addition, the lower edge drag-line that tradition is opened the string beam generally all exposes, and this seems that in some architectural environment some is lofty.
