2016年1月4日 · In that respect, HS-25 is an interpretation of the American Association of State Highway and Transportation Officials (AASHTO) HL93 truckload and is defined as being 20% higher than the HS-20 design truckload. Let’s take a deeper look:

An “H20” truck only has one axle under the trailer and a total load of 40,000 pounds. An “H25” or an “HS25” series truck will be almost identical – except the drive axle will be 10,000 pounds and the axle(s) under the trailer will be 40,000 pounds each. HL-93 - Design Vehicular loading per the AASHTO LRFD Bridge Design Specifications.

What is H-20/HS-20 Loading? AASHTO’s H-20 and HS-20 are live load ratings applied to the design of bridges or other suspended items (e.g. lids for concrete vaults). Because the pavers sit on a flat aggregate surface, they are not subject to the same bending moments and shear, and therefore will not collapse under the applied loads.

An “H25” or an “HS25” series truck will be almost identical – except the drive axle will be 10,000 pounds and the axle (s) under the trailer will be 40,000 pounds each. Figure 1 below illustrates the axle load and spacing breakdown for both HS20 and HS25 design trucks.

2015年1月26日 · HS25 is a 45T truck with the same axle configuration as HS-20. It came about 20 or so years ago to address the presence of heavier trucks and tandem vehicles. The decision to use HS-25 or HS-20 is up to the bridge owner. However, if you're designing a new bridge the requirement may very well be HL-93.

2017年6月13日 · AASHTO has established the following categories for weight limits for regular vehicular traffic: H20/HS20 = 16,000-lb wheel load, 32,000-lb axle. H25/HS25 = 20,000-lb wheel load, 40,000-lb axle. Covers designed to meet the basic requirements for these loads need only be tested with a proof load to meet these minimums.

2011年4月12日 · As a result, some engineers have required an “HS25” truck load rating for underground precast structures. This rating has been interpreted as being 25% higher than the HS20 truck load.

AstoCAD is a polished version of FreeCAD, with a cleaner interface and additional features that are not yet in FreeCAD. AstoCAD is a ‘soft-fork’ of FreeCAD. By soft we mean that AstoCAD is not really forking from FreeCAD. Instead it is always on top of FreeCAD.
