PCBRIDGE™ analyses the forces on a continuous beam over simple supports. Allows for differing stiffness and dead load between spans. Gives maximum moment, shear and deflection diagrams (and tabular output) using the 3-moment method. Also gives ENVELOPES for moving loads. Uses a 80x87 if present. Option for AASHTO or user-defined impact factor. Has 8 common vehicles and 10 user-defined vehicles.
PCBRIDGE™ has the following maximums:
    Number of spans = 10
    Number of concentrated loads = 16
    Total bridge length = 1020

PC-STRAN® performs a 1-,2-, or 3-dimensional structural analysis. Shows graphically the structure mesh, deformed structure, load, shear, moment, rotation and deflection member diagrams on graphics monitors. Powerful features include the ability to handle semi-rigid connections, zoom and rotate viewing angle, calculate member self-weight, extraploation of trapezoid member loads on member length or projected lengths (even on sloping members). Uses an 80x87 if present. Example input files.
PC-STRAN® has the following maximums:
    Number of member types = 64
    Number of member types (MASTER).PRP = 512
    Number of nodes (NN) = 128
    Number of members (NM) = 256
    Semibandwidth (IH) = 255
    Number of degrees of freedom (DOF) = 768
    Number of load cases (LC) = 8
    Number of members with linearly distributed loads = 128 (per load case)
    Number of records, K matrix (NR) = 32727*
    NR = [IH * (IH + 1)]/2 + IH *(DOF - IH)

*NOTE: Beginning with Version 5.00, PC-STRAN looks first to store the K matrix in EXTENDED memory. The Number of records is NOT limited to 32727 if there is enough EXTENDED memory. If there is no EXTENDED memory or not enough, then PC-STRAN will use conventional memory (below 640K limit). In conventional memory, the number of records IS limited to 32727.

PC-STRAN® version 6.00 requires extended memory and an 80x87. Example input files.
PC-STRAN® has the following maximums:
    Number of member types = 1000
    Number of member types (MASTER).PRP = 1000
    Number of nodes (NN) = 1000
    Number of members (NM) = 4000
    Semibandwidth (IH) = 6000
    Number of degrees of freedom (DOF) = 6000
    Number of load cases (LC) = 8
    Number of members with linearly distributed loads = 4000 (per load case)
    Number of records, K matrix (NR) = 18M*
    NR = [IH * (IH + 1)]/2 + IH * (DOF - IH)

*NOTE: Beginning with Version 6.00, PC-STRAN looks to store the K matrix in EXTENDED memory. If there is no EXTENDED memory or not enough, then PC-STRAN will end.

PC-DATA™ gives graphical and maximum likelihood parameter estimation of three general probability distributions (with or without suspended data) with user-specified confidence bounds:
  1. Two parameter Normal
  2. Two or Three parameter Lognormal
  3. Two or Three parameter Weibull

2weibull fits a two parameter Weibull distibution to the lower tail of a distribution with or without suspended data and calculates the 5th percentile of the distribution along with a data confidence factor.
