Coupled load analysis ek engineering concept hai jisme ek structure pe ek sath multiple types ke loads (forces ya moments) ka combined effect study kiya jata hai, jab ye loads ek dusre ke sath interact karte hain. Ye analysis structural design mein use hoti hai taki structure ki stability aur safety ensure ho sake.
- “Coupled” ka matlab hai loads ka ek dusre se juda hona ya milke kaam karna.
- Loads jaise axial force (push/pull), shear force, bending moment, torsion, ya thermal effects ho sakte hain.
- Jab ye loads ek sath lagte hain, toh ek load dusre ke behavior ko affect karta hai. For example, ek beam pe agar bending aur torsion dono hain, toh dono ka combined effect alag hoga compared to sirf ek load ke effect se.
Kahan use hota hai?
- Buildings, bridges, towers, ya aircraft structures mein.
- Earthquake ya wind loads ke analysis mein, kyunki ye forces ek sath multiple directions mein act karti hain.
- Finite Element Analysis (FEA) ya software jaise STAAD, ANSYS se iska calculation kiya jata hai.
Simple example:
Ek column pe agar vertical load (compression) aur side se wind load (lateral force) dono lag rahe hain, toh column ka bending aur buckling ek sath analyze karna padega. Ye coupled load analysis hai, kyunki dono forces ek dusre ke effect ko badha ya change kar sakti hain.
