Project scheduling program

This is a project scheduling program that allows you to make a full building or any other construction schedule. Features of the program include:

  • Creating new tasks and modifying them
  • Create connections between tasks (with options of FS – Finish Start and FF – Finish Finish)
  • Indenting tasks – creating WBS tree structure (WBS – Work Breakdown Structure)
  • Full undo and redo functionality
  • Import projects from Microsoft Project
  • History for every task performed
  • Input of financial data
  • Cash Flow diagrams based on financial data and schedule
  • Pie chart diagrams showing financial data per task bases
  • Exporting data as XML (with full history for each task)
  • Customizing columns
  • and some more…

One quick intro into the program and what it can do can be found here: .

Calculate moments in rectangular plates

This is a simple program for calculating moments in rectangular plates. As opposed to circular plates, we do not have exact equations for calculating rectangular plates. There have been a lot of experimental work done that have produced tables with which one can calculate moments in rectangular plates, depending on the boundary conditions (how is each of the 4 sides of the plate supported).

Program for calculating moments in rectangular plates

One of this kind of tables were made by Czerny, and which this program uses. User has to input the following:

  • uniform load on the plate – q
  • shorter dimension of the plate -lx
  • longer dimension of the plate – ly

According to the table selected in the top (which takes into account how the plate is supported) the program calculates moments Mx, My, Mxy, Mex and Mey.

When this is done, we can also select the type of concrete and steel, deformation of concrete and steel and thus calculate the minimum depth of the plate. Program also yields coefficients for Kd and Ks, from which we can determine how much steel we need for the plate to be safe (according to EC2).

Why would anyone need to use this program if we have so many computer programs for structural analysis? Well, we sometimes have to check if the results given by a sophisticated program is within values that we predicted. So if we know what the boundary conditions and the load of one plate is we can check what values we get with this program and compare the two results, if they both yield similar results than we can be assured that calculations by structural analysis were done correctly (i.e. everything was properly inputted into the program).
