For parametric bridge layout and design, also available as an integrated module with LEAP Bridge
LEAP GEOMATH is the only geometry application designed exclusively for bridge engineers for real-world projects of any scope and complexity, from single level crossings to multi-level complex interchanges with multiple horizontal alignments (including spirals) and vertical profiles simultaneously. LEAP GEOMATH keeps track of critical information pertinent to each project component. For example, if a pier is designed as perpendicular to an alignment, it will remain perpendicular even if the alignment is modified or the station of the pier is changed. More importantly, when an item's information is changed, LEAP GEOMATH automatically updates every related item in the data set, thereby maintaining the original design constraints throughout a project's lifecycle. Workflow associated with project alterations is therefore reduced and errors associated with redundant or multiple data entry are reduced or eliminated.
LEAP GEOMATH Data Sheet: View | Print
Covers full array of bridge types, design technologies and construction methods
Users may lay out conventional pre-stressed and post-tensions concrete girders, steel plate and steel rolled girders, as well as complex curved steel and segmental concrete box girders. Choose from pre-defined library sections or create new sections using powerful drawing tools. LEAP GEOMATH also offers a variety of automated tools for parametric structural framing and layout. Piers can be placed by station, bearing, or relative or offset position. Girders can be defined individually or in batches using offsets, bearing points, pier cap centerline, or other references.
Powerful design capabilities
Users may employ unlimited spans, piers and girders and specify multiple alignments and roadways (using a PI to PI or BC to EC segmental notations). LEAP GEOMATH handles curved girder layouts and piers with single or double bearing lines. Columns may have prismatic or non-prismatic sections. Users may calculate abutment, pier cap pedestal, beam seat, screed and final deck elevations at user-specified points along the span. Deck contours are generated to identify drainage areas of concern. Diaphragms and input beam cambers and deck deflections can be entered to calculate geometric information for ramps, including gore area. LEAP GEOMATH automatically locates abutment considering full slope requirements, structure depth and cross slope and beam design, and calculates material quantities, including deck concrete, haunch build up and deck reinforcing.
Parametrically adjusts changes in bridge geometry and component design
As a truly parametric solution, LEAP GEOMATH enables the placement of beam seats and bearings based on slab depth, haunch, or member plus bearing thickness, in relation to both the pier cap and girders, automatically adjusting the seat elevations for vertical curvature, camber and deflections. Users may copy, move or translate entire bridge models or selected data from one area to another.
Networking and import features enhance collaborative work environments
LEAP GEOMATH is a truly integrated and collaborative application, promoting greater productivity in a workgroup environment, regardless of the CAD platform employed. By importing data from CAD programs, LEAP GEOMATH simplifies the layout of bridge geometry because users are not required to recreate the work of roadway engineers. LEAP GEOMATH seamlessly imports DXF, DGN, Microsoft Excel, aerial photography, topographic information and tab-delineated input formats to aid in the collaborative processes.
Intuitive interface and 3D presentation aids in project visualization
LEAP GEOMATH's interface is highly visual and intuitive, using powerful relational abilities to compute elevations, deck contours, beams, girders and piers in stunning interactive 3D views. For complex interchange design, LEAP GEOMATH's relational power supports the creation and integration of multiple bridges in one file.
Comprehensive analysis and reporting to screen, paper, file or HTML
LEAP GEOMATH features a robust set of reporting options, covering finished deck grade elevations, vertical girder placement and geometry, four-corners beam seat elevations, or any one of 21 pre-defined reports. Or, create a custom report from the database. In addition, LEAP GEOMATH provides practical data for plan production, including plan, section and elevation detail. Reports can be exported to spreadsheet and tab-delineated file formats.
Wing Wall Layout
Abutment wing-walls can be laid out in LEAP GEOMATH. The wing-wall layout can be straight or curved and the bottom of the wing-wall can be controlled by a linear slope or an arbitrary ground surface. LEAP GEOMATH will automatically compute the required length of the wing wall.
Integral Pier Layout
LEAP GEOMATH can read and write integral pier data to LEAP CONBOX and transfer the pier data to LEAP RC-PIER. If a user defines a diaphragm at the pier, than the width of the diaphragm will be set equal to the integral pier width. If no diaphragm is defined at the pier then by default integral pier width will be set equal to the column width.
LEAP GEOMATH v7.1.0 features internal enhancements to enhance the interaction with LEAP Bridge and the other components (LEAP CONSPAN, LEAP RC-PIER and LEAP CONBOX). Many of its core geometric algorithms incorporating 3D points based on alignment, profile and cross section are used to accurately represent the 3D image within the LEAP Bridge viewer.
Read deflections from LEAP CONSPAN
LEAP CONSPAN now has the ability to write the final deflection to the database for all the beams if they are designed. Once that particular beam designed and its data is written in LEAP Bridge, LEAP GEOMATH is provided with an option to read that data from the LEAP Bridge database.
LEAP GEOMATH is a LandXML certified application. Using the transportation industry standard LandXML database format, LEAP GEOMATH has the ability to import data from other LandXML compliant applications such as AutoCAD, GEOPAK, InRoads and MicroStation 8.0.
