| WinHILO Bridge Deck Auto Load
Generator Software SOFTWARE FUNCTION
BRIDGE DECK MODELS Right, skewed and curved bridge deck models in 2D or 3D can be processed. Models may be created by WinFRAM, WinFELA or WinKWIK. Notional lanes are added to the model in WinHILO and loadings located by lane number, chainage and lateral offset are then applied. LOAD TYPES The load types allowed for in WinHILO are PATCH, POINT, UDL, LINEX, LINEY, AXLE, KEL and TS. In addition vehicle data may be recovered from a VEHICLES LIBRARY. Librarys for HB and fatigue vehicles and Eurocode EN1991-2 Special Vehicles are provided. Users may create there own Special Vehicles and vehicle trains. WinHILO LOAD TABLE ENTRIES Load table entries consist of a load type reference, a load distribution method (i.e. to nodes or to elements/members), a lane number, size/location/orientation values and the intensity. LOAD DISTRIBUTION WinHILO converts the loadings described by load type, lane number, chainage, offset, skew angle, intensity etc. to nodal or element/member loads. WinHILO refers to the conversion process as Load Distribution. Load Distribution discards any parts of a loading pattern which are outside the Deck Extent and warns the user of this. The Deck Extent can be specified as overhanging the deck model edges - any loading in this area is transferred to the edge nodes/members by cantilever action. WinHILO GRAPHICS Screen graphics provide a visual validation of data entered. Location of Notional Lanes can be checked and loadings viewed in both pre- and post-distributed format. INFLUENCE SURFACE CREATION Influence surfaces can either be created by specifying WinFRAM/WinFELA distortion and settlement loadcases or, now, from within WinHILO by just pointing to a location and chosing the effect to be studied there. CRITICAL CHAINAGE ANALYSIS This procedure moves an WinHILO load pattern across the bridge and determines the most adverse position for the loading and the value of the controlling effect. ADVERSE PATTERN GENERATOR Allows the designer to confidently create the most adverse pattern of traffic loading on the bridge. This automatic procedure considers all possible combinations of UDL/KEL/abnormal vehicle types/positions or LM1 UDL/LM1 TS/Special Vehicle (depending on the Design Code selected) and adverse pattern factors. All parameters used are user-selectable to override the otherwise automatically selected values. WinHILO generates adverse patterns for moment, shear, torque, axial load and reaction and calculates the value of the controlling effect. BULK ADVERSE PATTERN GENERATOR This feature allows up to 100 positions and effects to be considered in a one-step computation. This means that applied load design envelopes can now be produced very efficiently, for example the bending moment envelope for a beam from one abutment to the other. A true time-saver! |
