Frame Analysis 2D Calculator

A high-quality 2D frame analysis calculator for civil engineering professionals. Calculate structural frames with precision and reliability.

Beam Inputs

Point Load P (kN)

Span Length L (m)

Elastic Modulus E (GPa)

Moment of Inertia I (m^4)

Midspan Displacement

0.0000 m

How to use

Enter the point load, span length, modulus of elasticity, and moment of inertia. The calculator estimates midspan displacement for a simple frame element.

Methodology

The calculator uses the standard displacement formula for a simply supported beam with a central point load.

Full original guide (expanded)

The calculations are based on the engineering principles outlined in the ASCE 7-22 standard. Consider a frame with a length of 6 meters and a load of 20 kN. Using the formula \( \text{Displacement} = \frac{PL^3}{48EI} \), you can calculate the displacement based on material properties.

FAQ: Can I use this calculator for 3D frames? No, this calculator is specifically designed for 2D frame analysis. For 3D analysis, consider using specialized software.

Formulas

\[\delta = \frac{PL^3}{48EI}\]
