I built a short presentation demonstrating the use of CodeSkulptor3 (Python 3). This time, my goal was to illustrate coding a small probability problem including a plot of results — accessible from any device — desktop, phone, iPad. Feel free to follow the links and to offer a critique. Probability of finding exactly one digit […]

Multi-Page Apps using Dash/PythonAnywhere Apr2020
I have completed a couple more apps using Dash by Plotly This time, my goal was to build the apps on the web — accessible from any device – desktop, phone, iPad. Now, I have a full proof of concept. Feel free to follow the links and to offer a critique. AISC Strong Axis Bending […]
WT Braces Mar 2020
In the petrochemical business, it is quite common to see structural steel braces built from WT shapes. If you like Table 4-12 in the AISC 15th Edition, then you might like the attached example plots which I built on the same principle. AISC 15th Edition LRFD maximum axial capacities in kips; KL in feet Maximum […]
Calculate Beta w for Single Angles Dec 2019
AISC v15.0 Shapes Database # NOTE # For enhanced readability and easier translation to other software, # exponents are indicated with the (mathematically) traditional caret symbol. # In Python, replace all carets with a double asterisk. # Get single angle properties a = np.arctan(my_angle.TANA) c = np.cos(a) s = np.sin(a) b = my_angle.B_LOWERCASE d = […]
Structural Property Calculator — Improved Dec 2019
# calc> ddet(..w8x31) # not case sensitive 8.0 # # On assignment, now, the calculator # returns __str__(object) # the string representation of the object # # Therefore, # On assignment of an AISC shape the calculator # returns __str__(shape) # the string representation of the shape # calc > a = ..w8x31 # not […]
Python — Nested Ifs Nov 2019
NESTED IFs: A question was asked recently on Stack Overflow The solution shown below is readable, scalable, easily edited — and contains no IF statements. This is similar to the method proposed by Anitoliy R except I use a single string and the split function to simplify editing and scaling. To illustrate scalability, I add […]
