With this program you will be able to easily calculate structures with the methods Matricial and Cross with the 49G. It has been made specifically for industrial engineering at the University Miguel Hernandez. Messes with your calculator's settings.
This program determines for a two-way slab supported on the left, right, and bottom edge (top edge unsupported) the significant bending moments. The supports may be hinged and/or clamped in any order. Accepted load types are: area load q, triangle-shaped load qTri, and line load on top edge qR. The ratio ly/lx must be in the range of 0.25 and 1.5. Includes now variable load factors. Tested on both the 49g+ and 50g.
Topography program with polygons and more. Only works on the original 49G.
This small program allows you to make surveying, leveling and more in the field. Very useful.
Calculates diverse elements of topography like area by coordinates, conversions of area, double radiation, calculation of azimuths, tachymetry, corrections by catenary and traction, etc.
Topography library for both new and old students of the matter. Contains a great variety of programs that could be of use for university students of civil engineering.
Programming manual for using the separate 
Program for closed polygon calculation for topography. Requires the user to enter the internal angles (without compensation) and the distance between the sections, and also the azimuth (direct or reverse) on either side of the polygon, and the coordinate of any topographic point in the polygon.
Civil engineering program for the course Topography II.
Calculates the bench marks for risings in all type of levelings, curved areas, polygon coordinates (area and perimeter), and areas of triangulations.
Performs calculations on tools for network; could be useful for land surveyors.
Civil engineering program that works with tangents, coordinates, distance between points, slopes, and more.
Structural engineering application which can calculate the following things of any given truss: member elongations, member normal force, member normal stress, nodal displacements, and reaction forces. Written in System RPL (includes source code) with some assembly language and includes a comprehensive manual in Word format. SR2 includes Spanish HP 49 library.
Three-dimensional analysis of hyperstatic and static truss with the finite element method.
Calculate losses and volume flow rate in nets with pipes (1 to 14). Also handles series and parallel, finds any variable in single pipe, and finds physical properties of liquid water at any temperature.
Contains the properties of polyethylene pipes.
This program calculate four different cycles from gas turbine (Brayton Cycle).
The program determines for a two-way slab supported on all edges the moments and bearing reactions on the method of PIEPER/MARTENS. All kinds of support conditions (hinged and/or clamped in any order) are provided. It now offers a wider range for the ratio Ly/Lx and a more comfortable handling for compensation between neighboring restraint moments. For both the 49 and 50.
Converts coordinates given in UTM (map datum: WGS 84) into those of the German Potsdam Datum (Gauss-Krueger or Longitude/Latitude) and vice versa. Additionally the numbers of the corresponding German "Messtischblatt" plus the accompanying quadrants/subquadrants are output. For the conversion using UTM values, the program Geodesia 1.03 (library number 1213) is required. For both the 49 and 50.
Allows the conversion between the UTM coordinate system the and geographical coordinate system.
Performs material resistance calculations by taking a square matrix and calculating its eigenvectors and eigenvalues, just like EGV, but it changes the vectors for the unitary ones (with the same direction) and, if three-dimensional, checks if they form a direct reference system..
Program to calculate bond and overlapping of reinforcement steel according to German DIN 1045-1.
I have no idea what this stupid program does because the author was too lazy to submit a description or write any documentation. I think it's for discharge formulas for hydraulics.
Asks you for the coordinates east and north of a point, and the distance and azimuth to each other, and it calculates the coordinates of the other point.
Practice program to calculate curved circular and hairsprings with several options and with 4 connections and graphics.
Calculates the mass matrix, stiffness, flexibility, dynamic, eigenvalues, periods, frequencies and modes as both spring beams. Uses the Duhamel algorithm.
Structural analysis program for all types of beams.
Program for calculating and dimensioning rectangular beams.

Solves beams for structural engineering.
This program calculates the factors of transport, absolute rigidity, and embedding moments in beams of variable section. It calculates everything for Hardy Cross.
Design of beams of reinforced concrete, based on the "Normas Técnicas Complementarias del Reglamento de Construcciones del Distrito Federal" (NTC87 of the regulation of constructions of Mexico City).

Usually in construction cost analysis or in structural design an engineer needs to know the weight of a steel section. This program helps you calculate the weight of a variety of sections, like rebar (both metric and standard) round and rectangular pipes, and an option to input the section area if you know it. Now the calculated numbers are exact, so there is no longer a need to consult the ASTM tables. Results are put on the stack in different units of linear weight, where you can PICK the one suited to your needs in your calculations.
