However, the user can convert this loadings into a static load case in which actual positions of 4 wheels are taken into account. In moving load tracer, the wheel loads will be placed to the centerline of each truck for allthe axles. Therefore, the wheel spacing in Traffic Line/Surface Lanedialog box should be entered considering the distance between the centerlines of two trucks. In the program, only two wheels are allowed in one axle. Moving Load Analysis to Polish Standard (continued) Limitation for vehicle 2S: One axle of Vehicle 2S consists of 4 wheels.

Averagespan length can automatically be calculated using “Span Start” option in Traffic Line/Surface Lane dialog box. For multi-span bridges, average span length is applied as specified in Polish Standard. Dynamic amplification factor can automatically be calculated considering span length. Vehicle K, Vehicle S, Vehicle 2S and user-defined vehicle can be selected. Moving Load Analysis to Polish Standard Vehicle database for road bridges and pedestrian bridges as per PN-85/S-10030 has been newly implemented. Thus, the partial factor for the vehicleshould be applied in the load combination.Moving Load Case Dialog BoxMoving Load Case Dialog Box4 / 20Ĭivil 2017 Analysis & DesignCivil 2017 (v1.1) Release Note2. Without partial factorWhen only one type of vehicle is applied for the assessment of bridges, the ‘Auto LiveLoad Combination’ option is not supported.

HA loads defined to BD 21/01 can be combined with special vehicles (SV, SOV) as per BD 86/11.
For assessment purposes the HA loads are factored to give the Assessment Live Loading.
Assessment loading is generally limited to the application of dead and superimposeddead loads and the type HA live loads. Assessment Live Loading to BD 21/01 BD 21/01 is intended to be used for the assessment of highway bridges and structures in the UK. : Civil 2017 (v1.1)DESIGN OF CIVIL STRUCTURESInt egrat edSolutionSyst emforB ridgeandCivilEngineeringĮnhancements Analysis & Design1)Assessment Live Loading to BD 21/012)Moving Load Analysis to Polish Standard3)Moving Load Optimization to Russian Standard4)Auto-generation of Load Combinations to Polish Standard5)PSC Composite Section Design to Indian Standard6)Linear independent stage analysis7)Time Dependent Materials as per New Zealand Standard8)Time Dependent Materials as per Australian Standard Pre & Post-Processing1)Addition of PSC Super-T and I-girder Section DB2)Critical stress locations due to warping for PSC section type318Ĭivil 2017 Analysis & DesignCivil 2017 (v1.1) Release Note1.
