Castigliano's method for calculating displacements is an application of his second theorem, which states: If the strain energy of a linearly elastic structure can be expressed as a function of generalised force Q i then the partial derivative of the strain energy with respect to generalised force gives the generalised displacement q i in the direction of Q i.
The finite strip method is a technique of structural analysis used for bridge and tall structure design as well and in the design of construction components such as steel beams. The technique was first introduced in 1968 and is less powerful and versatile than the finite element method but is more efficient in terms of computation power in some ...
A classification for the structural system of a high-rise was introduced in 1969 by Fazlur Khan and was extended to incorporate interior and exterior structures. The primary lateral load-resisting system defines if a structural system is an interior or exterior one. [2] The following interior structures are possible: Hinged frame; Rigid frame
One of the largest areas to utilize the direct stiffness method is the field of structural analysis where this method has been incorporated into modeling software. The software allows users to model a structure and, after the user defines the material properties of the elements, the program automatically generates element and global stiffness ...
The original works such as those by Argyris [4] and Clough [5] became the foundation for today’s finite element structural analysis methods. Straight or curved one-dimensional elements with physical properties such as axial, bending, and torsional stiffnesses.
Structural dynamics is a type of structural analysis which covers the behavior of a structure subjected to dynamic (actions having high acceleration) loading. Dynamic loads include people, wind, waves, traffic, earthquakes, and blasts. Any structure can be subjected to dynamic loading.
Structural reliability is about applying reliability engineering theories to buildings and, more generally, structural analysis. [ 1 ] [ 2 ] Reliability is also used as a probabilistic measure of structural safety.
Seismic analysis is a subset of structural analysis and is the calculation of the response of a building (or nonbuilding) structure to earthquakes. It is part of the process of structural design , earthquake engineering or structural assessment and retrofit (see structural engineering ) in regions where earthquakes are prevalent.
