Example of Solving a Set of Coupled, Non-linear Equations with UnitsThis worksheet illustrates PTC Mathcad's ability to solve a set of nonlinear coupled equations for several unknowns, where the unknowns each have different units.
Finding Channel Height, Channel Width, and Velocity of WaterThis worksheet using PTC Mathcad models the low water crossing geometry as a trapezoid to find the height, width, and velocity of the water in a channel.
Finding the Shear Force and Bending Moment Along a BeamThis worksheet using Mathcad provides you with an example of how the shear force and the bending moment along a simply supported beam can be determined as a function of the distance from one end.
Inelastic Effective Length FactorsComputes the stiffness reduction factors for inelastic behavior (Table A, page 3-8 of the AISC Manual), the stiffness ratios at the ends of the column (G values), and the effective length factor k for sidesway permitted.
Material Properties, Development, and Splice Lengths Determines factors and properties and defines constants required to compute shear strength, flexural strength, minimum thickness, and the development and splice lengths of reinforcing bars.
Measuring Traffic Flow and EAL for VehiclesThis worksheet using PTC Mathcad performs calculations to measure the traffic flow and evaluation assurance level for normal trucks and construction vehicles. The EAL is a security evaluation that measures functional, structural, and methodological efficiency for an IT system and in this instance is applied for vehicles.
Moment MagnificationComputes moment magnifiers for a square or rectangular column, either subject to sidesway, or braced to prevent appreciable sidesway. Moments computed by an ordinary first order frame analysis are then multiplied by the applicable moment magnifier to obtain the moments to be used for design.
Pile Cap ConfigurationsCalculates pile coordinates and pile cap plan dimensions for pile groups with 2 to 20 piles.
Pile FootingsDetermines minimum required pile cap thickness and the maximum size and minimum number of reinforcing bars for pile caps with from 2 to 20 piles in a group.
Rectangular Tied ColumnsDetermines the complete range of usable factored axial load and moment for a square or rectangular column of any size, reinforced with any number and size of reinforcing bars, and with any concrete and reinforcement strengths permissible.
Reinforced Concrete Beams: Size SelectionDetermines the sizes of rectangular beams to satisfy the flexural requirements, shear requirements and minimum thickness limits of ACI 318-89.
