Moment-Curvature Simulator
Structural Analysis & Plastic Design
Compute the moment-curvature (M-φ) relationship of a rectangular beam section under bending. Adjust the section size, yield stress and curvature ratio to see the yield m…
Joint Moment Distribution Simulator — Hardy Cross Basics
Structural Analysis & Plastic Design
From the member lengths at a rigid joint, compute the relative stiffness K=1/L and distribution factors DF, then watch how an applied moment M_0 is shared among the thre…
P-Delta Amplification Simulator
Structural Analysis & Plastic Design
Use this page to relate representative assumptions to nearby design assumptions and key metrics before moving into the adjacent engineering checks.
Plastic Hinge Collapse Load Simulator
Structural Analysis & Plastic Design
A ductile beam does not fail the instant its first section yields. Plastic hinges form one by one, and the structure collapses only when it becomes a mechanism. Change t…

Structural Analysis & Plastic Design
Explore how much reserve a beam section keeps between \
Shear Wall Lateral Stiffness Simulator
Structural Analysis & Plastic Design
Calculate the lateral stiffness of a shear wall that resists the horizontal loads from earthquakes and wind.
Structural Reliability Analysis & Probability of Failure Calculator
Structural Analysis & Plastic Design
Compute reliability index β & failure probability Pf via FORM or Monte Carlo simulation. Visualize R-S interference & required mean resistance for target reliability.
Yield Line Theory Simulator — Ultimate Load of a Rectangular Slab
