<jats:p> The construction process is a time-consuming and dynamic process subject to a changing environment. The time and path influence should be considered for a more exact result on its mechanical behavior, especially for large-span spatial structures. This article presents a structural analysis framework called the vector form intrinsic finite element for construction simulations. The vector form intrinsic finite element based on vector mechanics is different from the traditional finite element method, which is developed from continuum mechanics. It is easy to solve problems involving nonlinearity without establishing the equilibrium matrix. The construction process, such as erection of cables, is accompanied by mechanisms and rigid body motions. Furthermore, a new element, named the traction cable element, is proposed to analyze the lifting process, and the expression of the internal element force is derived. The results obtained from the lifting of a single cable illustrate that vector form intrinsic finite element can produce an accurate analysis result. Finally, analysis of a practical project shows the capability of vector form intrinsic finite element in the construction simulation of a cable–strut–beam steel structure. </jats:p>

<jats:p> Buildings can be designed to limit the earthquake-induced damage to members that can easily be repaired. Self-centering moment-resisting frames can be used as effective structural systems for this purpose. Self-centering moment-resisting frames with prestressed cables are able to return the structure to its original position after the earthquake. The internal forces in self-centering moment-resisting frames are transferred between the beam and the column by post-tensioned cables. As a main member of self-centering connections, prestressed cables play a significant role in such systems. Cable tension decreases over time due to the effect of stress relaxation on the performance of the system. Stress relaxation is a time-dependent phenomenon causing stress reduction over time in the members prestressed at a constant strain. Therefore, the effect of stress relaxation on the performance of self-centering moment-resisting frames can be significant. In this article, after simulating and validating a moment-resisting frame with self-centering connections, stiffness and moment–rotation hysteresis diagrams were analyzed after 0, 1, 5, 10, and 20 years of cable prestressing. According to the results, two equations were presented to estimate the reduction in the connection stiffness and dissipated energy by the system based on prestressing level and the time after prestressing. The proposed equations could be used to model semi-rigid connections. </jats:p>

<jats:p>This article presents a literature review of existing research on the strong column–weak beam design philosophy, which has been widely adopted in the seismic design of frame structures. A comprehensive review of this design philosophy, including its concept and research history, especially factors affecting the accurate calculation of the flexural capacity of beams [Formula: see text] and the determination of the column-to-beam flexural strength ratio [Formula: see text], is presented first. The development of design provisions of four representative countries for this design philosophy is also reviewed. The implementation of strong column–weak beam hierarchy in real structural design is then discussed, and existing problems are pointed out. Finally, different techniques for the seismic retrofit of existing reinforced concrete frames are reviewed.</jats:p>
