Comprehensive Program for the Analysis and Design of Concrete Beams


Ventajas

Easy-to-Use Interface

The easy-to-use interface simplifies design. LEAP PRESTO has an intuitive interface that uses a convenient system of tabs, drop-down menus and icons, making project data entry quick and simple. LEAP PRESTO's graphical modeling features make viewing and interpreting analysis and design results an easy task.

Comprehensive Design Capabilities

In LEAP PRESTO, the sections that can be designed are double tee, single tee, inverted tee, L-beams, I-girders, hollow core, solid slab or joist beams. A graphic editor lets you define intricate custom cross-sections. Members are assumed to be simply supported and can have unequal cantilevers at either or both ends. Rectangular or circular flange openings can be introduced into a member, and the resulting section properties are automatically computed. Topping thickness can vary along the length of a member in a stepped fashion. If the topping is eccentric with respect to the centerline of a member, its eccentricity can be specified for computation of the torsional effects.

Complete Reinforcement Options and Types

Reinforcement options include low-relaxation or stress-relieved strands, and rebar. LEAP PRESTO can automatically generate strand and debonding patterns (symmetrically or asymmetrical), and they may be straight or depressed. Rebar may be in the precast section or in the topping, and may also be straight, hooked or mechanically-anchored at the ends.

Powerful Analysis Features

LEAP PRESTO analyzes all code-specific areas of design, including stress checks at release and final conditions, ultimate strength checks, combined shear and torsion steel design, horizontal shear steel design, and camber calculations. Loads can be point, uniform or trapezoidal, and can be of constant or linearly varying magnitude. Loads can also be applied fully or partially along a member. Analysis options include bearing design, transformed strands, live load recapture, and bilinear deflection.

Report Generation and Export

LEAP PRESTO offers user-friendly report generation and export. It generates numerous high-quality reports in both text and graphic format. You can export the graphics to DXF format and the results to spreadsheets.
