Compared to concrete for conventional construction, mixes for 3D printing must satisfy more stringent requirements to achieve pumpability, extrudability, and buildability. This study reviews the rheological, mechanical, and durability properties of mortar-based 3DPC. The effect of incorporating coarse aggregates in 3DPC mixes on the shrinkage and bond strength of printed elements is also discussed. Mortar-based 3DPC is characterized by a lower self-weight which enhances interlayer stability. However, mortar-based 3DPC exhibits high shrinkage compared to aggregate-based 3DPC. Both a retarder and high-range water-reducing admixtures may be necessary to control the flowability and setting time of 3DPC. The study focuses on the effects of binder composition, aggregate size, water-to-binder ratio, reinforcement, and printing parameters on pumpability, extrudability, and buildability.

To address the need for rapid assessment, a Stacking model-based seismic resilience evaluation model for bridge networks is developed. The integration of Stacking and GAN models addresses the issue of insufficient training data while simultaneously improving the model’s prediction accuracy and generalization capability. Additionally, using a parametric modeling approach for bridges and based on 14 urban road networks, a sample library containing 5000 bridge networks was established using a GAN model. Finally, using a bridge network from a region in Anaheim as an example, the structural and functional resilience of the network was assessed.

Regarding the optimal parameters of TVMD and the corresponding optimal control effect of the PIS scheme, the variation rules under the influence of SS parameters are investigated and compared with the other conventional schemes.

To achieve this, companion spectra for fling motions are constructed and compared to other existing options, such as RotDpp, MaxRotD50, etc. Nonlinear dynamic analyses of structures, modeled using an established fiber formulation, show that the mean response to actual bidirectional shaking—across several real records—can be estimated with low dispersion by using fewer records independently matched with the companion spectra.

Among others, energy-based approaches have demonstrated significant potential in identifying limit states, due to their enhanced physical coherence in nonlinear response interpretation. This study presents a methodology that employs absorbed internal energy and power to characterize the seismic capacity of structural elements. Two key challenges are addressed: (i) the identification of the impulsiveness associated with individual energy “jumps” in the hysteresis loop and (ii) the quantification of energy dissipated at each jump, which are aspects often insufficiently addressed in existing literature. To this end, two energy parameters are defined to highlight, within a response function, the most significant contributions in terms of dissipation (D) and impulsivity (I). The effectiveness of the methodology is validated through the analysis of an extensive experimental database of reinforced concrete columns subjected to cyclic loads. The results demonstrate enhanced precision in capturing damage levels compared to traditional approaches.
