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 pcbridge.zip v 2.80 1996 94Kb |

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.zip v 5.02 1994 417Kb |

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.

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.See ASTM D 5457 – 04a "Standard Specification for Computing Reference Resistance of Wood-Based Materials and Structural Connections for Load and Resistance Factor Design" 2weibull.zip v 1.50 1993 45Kb |
