It is one subset of structural analysis. Structural mechanics analysis needs input data such as structural loads, the structure's geometric representation and support conditions, and the materials' properties. Output quantities may include support reactions, stresses and displacements. Advanced structural mechanics may include the effects of stability and non-linear behaviors. Mechanics of structures is a field of study within applied mechanics that investigates the behavior of structures under mechanical loads, such as bending of a beam, buckling of a column, torsion of a shaft, deflection of a thin shell, and vibration of a bridge. There are three approaches to the analysis: the energy methods, flexibility method or direct stiffness method which later developed into finite element method and the plastic analysis approach. == Energy method == Energy principles in structural mechanics == Flexibility method == Flexibility method == Stiffness methods == Direct stiffness method Finite element method in structural mechanics == Plastic analysis approach == Plastic analysis == Major topics == Beam theory Buckling Earthquake engineering Finite element method in structural mechanics Plates and shells Torsion Trusses Stiffening Structural dynamics Structural instability == References == - [[Professional Practice/Codes & Standards/National Building Code of India/Part 06 - Structural Design]] - [[Professional Practice/Codes & Standards/Structural Codes]] - [[Building Construction/Structural Systems]] - [[Structures/Structural Engineering]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 06 - Structural Design/Section 1 - Loads Forces and Effects]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 06 - Structural Design/Section 2 - Soils and Foundations]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 06 - Structural Design/Section 3A - Timber]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 06 - Structural Design/Section 3B - Bamboo]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 06 - Structural Design/Section 4 - Masonry]] - [[Professional Practice/Codes & Standards/National Building Code of India/Part 06 - Structural Design/Section 5A - Plain and Reinforced Concrete]]
