Structural Engineering Overview

Principles

Definition

Structural engineering is a research field and applied discipline focused on the analysis, design, and construction of structures that safely resist loads and environmental forces. It investigates the mechanical behavior of materials and structural systems to ensure their stability, durability, and serviceability throughout their intended lifespan.

Nonlinear Failure Modeling era

J. R. Rice [1], associated with Harvard University [3] and the Massachusetts Institute of Technology [4], was a foundational figure in nonlinear failure modeling during this era. His 1968 paper 'A Path Independent Integral and the Approximate Analysis of Strain Concentration by Notches and Cracks' [6] and the 1969 paper 'On the ductile enlargement of voids in triaxial stress fields' [7] advanced path-independent formulations and void-growth concepts that underpinned stability and fracture analyses in energy-based frameworks of the period. F. Erdoğan [2], affiliated with Lehigh University [5], produced foundational crack propagation analyses during this era, with papers including 'A Critical Analysis of Crack Propagation Laws' [8], 'On the Crack Extension in Plates Under Plane Loading and Transverse Shear' [9], and 'Crack-Tip, Stress-Intensity Factors for Plane Extension and Plate Bending Problems' [10]. Erdoğan [2]'s crack propagation work, together with the broader nonlinear framework of the era, contributed to shaping the fracture mechanics corpus by formalizing crack-tip fields, propagation criteria, and their integration into energy-based instability concepts.

Composite Confinement Retrofit era

M. J. N. Priestley [1], with affiliations at University of California, San Diego [3] and University of Pavia [4], emerged as a foundational figure in the composite confinement retrofit era. His Theoretical Stress‐Strain Model for Confined Concrete [7] established a mechanistic basis for FRP-confined designs and informed early confinement practices in this era. J.G. Teng [2], with affiliations at University of Hong Kong [5] and Hong Kong University of Science and Technology [6], advanced FRP-confined concrete modeling through key papers such as Analysis-oriented stress–strain models for FRP–confined concrete [8] and Refinement of a Design-Oriented Stress–Strain Model for FRP-Confined Concrete [9]. His final contribution, Theoretical Model for Fiber-Reinforced Polymer-Confined Concrete [10], together with ongoing work, provided a coherent theoretical framework that strengthened design-oriented and damage-based retrofit guidance during this era.

Additive and Sustainable Concretes era

Marko Sarstedt [1] is a leading scholar in structural equation modeling affiliated with Ludwig-Maximilians-Universität München [3] and the University of Newcastle Australia [4] in this era. His paper on Partial Least Squares Structural Equation Modeling: Rigorous Applications, Better Results and Higher Acceptance [7] contributed rigorous, accessible methods for analyzing complex, interdisciplinary data, enabling more reliable evaluation of process-aware design and sustainability metrics in additive and sustainable concretes. Christian M. Ringle [2] is a prominent scholar at James Cook University [5] and Universität Hamburg [6] in this era. Together with Partial Least Squares Structural Equation Modeling: Rigorous Applications, Better Results and Higher Acceptance [7], Christian M. Ringle [2] helped disseminate and apply PLS-SEM to structural and sustainability-related research, supporting robust model-based assessment for additive manufacturing and sustainable concretes.
