Structural engineering is a sub-discipline of civil engineering in which structural engineers are trained to design the 'bones and joints' that create the form and shape of human-made structures. Structural engineers also must understand and calculate the stability, strength, rigidity and earthquake-susceptibility of built structures for buildings and nonbuilding structures. The structural designs are integrated with those of other designers such as architects and building services engineer and often supervise the construction of projects by contractors on site. They can also be involved in the design of machinery, medical equipment, and vehicles where structural integrity affects functioning and safety. See glossary of structural engineering.

Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes. With better understanding of seismic demand on structures and with recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged. Prior to the introduction of modern seismic codes in the late 1960s for developed countries and late 1970s for many other parts of the world, many structures were designed without adequate detailing and reinforcement for seismic protection. In view of the imminent problem, various research work has been carried out. State-of-the-art technical guidelines for seismic assessment, retrofit and rehabilitation have been published around the world – such as the ASCE-SEI 41 and the New Zealand Society for Earthquake Engineering (NZSEE)'s guidelines. These codes must be regularly updated; the 1994 Northridge earthquake brought to light the brittleness of welded steel frames, for example.
NASTRAN is a finite element analysis (FEA) program that was originally developed for NASA in the late 1960s under United States government funding for the aerospace industry. The MacNeal-Schwendler Corporation (MSC) was one of the principal and original developers of the publicly available NASTRAN code. NASTRAN source code is integrated in a number of different software packages, which are distributed by a range of companies.
Earthquake engineering is an interdisciplinary branch of engineering that designs and analyzes structures, such as buildings and bridges, with earthquakes in mind. Its overall goal is to make such structures more resistant to earthquakes. An earthquake engineer aims to construct structures that will not be damaged in minor shaking and will avoid serious damage or collapse in a major earthquake. A properly engineered structure does not necessarily have to be extremely strong or expensive. It has to be properly designed to withstand the seismic effects while sustaining an acceptable level of damage.

Autodesk Revit is a building information modelling software for architects, structural engineers, mechanical, electrical, and plumbing (MEP) engineers, design for contractors. The original software was developed by Charles River Software, founded in 1997, renamed Revit Technology Corporation in 2000, and acquired by Autodesk in 2002. The software allows users to design a building and structure and its components in 3D, annotate the model with 2D drafting elements, and access building information from the building model's database. Revit is 4D building information modeling application capable with tools to plan and track various stages in the building's lifecycle, from concept to construction and later maintenance and/or demolition.
Navisworks is a 3D design review package for Microsoft Windows.
NEi Nastran was an engineering analysis and simulation software product of NEi Software. Based on NASA's Structural Analysis program NASTRAN, the software is a finite element analysis (FEA) solver used to generate solutions for linear and nonlinear stress, dynamics, and heat transfer characteristics of structures and mechanical components. NEi Nastran software is used with all major industry pre- and post-processors, including Femap, a product of Siemens PLM Software, and the in-house brands NEi Nastran in-CAD, NEi Fusion, and NEi Works for SolidWorks. This software was acquired by Autodesk in May 2014.
RUCAPS was a computer aided design (CAD) system for architects, first developed during the 1970s and 1980s, and today credited as a forerunner of Building Information Modelling (BIM). It ran on minicomputers from Prime Computer and Digital Equipment Corporation (DEC).
Tekla is a software product family that consists of programs for analysis and design, detailing and project communication. Tekla software is produced by Trimble, the publicly listed US-based technology company.
Tekla Structures is a building information modeling software able to model structures that incorporate different kinds of building materials, including steel, concrete, timber and glass. Tekla allows structural drafters and engineers to design a building structure and its components using 3D modeling, generate 2D drawings and access building information. Tekla Structures was formerly known as Xsteel.
The table below provides an overview of notable computer-aided design (CAD) software. It does not judge power, ease of use, or other user-experience aspects. The table does not include software that is still in development. For all-purpose 3D programs, see Comparison of 3D computer graphics software. CAD refers to a specific type of drawing and modelling software application that is used for creating designs and technical drawings. These can be 3D drawings or 2D drawings.
STAAD or (STAAD.Pro) is a structural analysis and design software application originally developed by Research Engineers International (REI) in 1997. In late 2005, Research Engineers International was bought by Bentley Systems. STAAD stands for STructural Analysis And Design.
S-FRAME Software Inc., formerly SOFTEK Services Ltd. is a Canadian engineering software company that develops analysis and design software for use by civil and structural engineers. S-FRAME was founded in 1981 by George Casoli, FCSCE, P.Eng. The company was acquired in 2021 by Altair Engineering.
RFEM is a 3D finite element analysis software working under Microsoft Windows computer operating systems. RFEM can be used for structural analysis and design of steel, concrete, timber, glass, membrane and tensile structures as well as for plant and mechanical engineering or dynamic analysis and analysis of steel joints.
A windpost is a structural item used in the design and construction of masonry walls to increase lateral wall stability and protect them against damage from horizontal forces imposed by wind pressure, crowd or handrail loads. They are normally constructed from mild steel channel sections, supported at the head and the foot between floor slab levels and/or the principal steelwork sections forming the structural frame of the building. In cavity walls, the windpost will typically be fixed into the inner and outer leafs of the wall by specialist fixings and fastenings at regular intervals along its length. The windposts will be spaced along the walls of the building at regular intervals as calculated by the engineer to suit the required loadings.
