🏗️ DETERMINATE vs INDETERMINATE STRUCTURES | Structural Analysis
Understanding whether a structure is statically determinate or statically indeterminate is one of the fundamental concepts in structural analysis. It helps engineers determine which analysis methods are appropriate and how a structure responds to loads and support conditions.
🔹 1. STATICALLY DETERMINATE STRUCTURE
A structure is statically determinate when all support reactions and internal forces can be determined using the equations of static equilibrium alone.
📌 Key Features:
• Equilibrium equations are sufficient
• Compatibility equations are not required to determine the reactions
• Generally simpler and faster to analyse
• Results do not depend on member stiffness for basic force determination
🏗️ Examples:
• Simply supported beams
• Cantilever beams
• Basic statically determinate trusses
