This study proposes an intelligent layout design method for beams of reinforced concrete shear-wall structures based on deep neural networks. By learning the implicit laws of existing designs and generating new layout schemes, this method improves design efficiency and achieves comparable results to competent engineers.
Beam and slab design is a critical component of shear wall structure design. Currently, conventional manual design is time-consuming, and defining objective functions and design variables of an optimization design is challenging. In contrast, deep learning methods can learn high-dimensional image features and generate new designs, providing new solutions for efficient and intelligent structural design. Therefore, based on deep neural networks, this study proposes an intelligent layout design method for beams of reinforced concrete shear-wall structures using the input of fused building space and element attributes. This method learned the implicit laws of existing designs and realized the inferential generation of new layout schemes. Subsequently, based on mathematical statistics, methods to determine the type and size of coupling and frame beams are proposed. A typical case study shows that the structural performance of the beam and slab designed by this method was comparable to that of competent engineers. The maximum inter-story drift ratio of the result designed by the proposed method differs from that designed by engineers by no more than 5 x 10(-5). The differences in the maximum vertical typical-floor-slab displacement, the concrete consumption, and the steel consumption between the design result of the proposed method and the engineer's design result are 0.8%, 2.88%, and 6.20%, respectively. Moreover, the design efficiency was significantly improved by more than 30 times.

Intelligent design of shear wall layout based on graph neural networks

Pengju Zhao, Wenjie Liao, Yuli Huang, Xinzheng Lu

Summary: The structural scheme design of shear wall structures is of great importance as it guides the whole structural design process and has a significant impact on subsequent design stages. Current design methods based on deep generative algorithms using pixel images have certain flaws and limitations, such as excessive model parameters and difficulty in reflecting topological characteristics of structures. This study proposes the use of graph neural networks (GNNs) to represent shear wall structures in graph data form and develops an intelligent design method based on GNNs, addressing the existing problems and limitations in shear wall layout design.

Melanocortin receptor agonist NDP-α-MSH improves cognitive deficits and microgliosis but not amyloidosis in advanced stages of AD progression in 5XFAD and 3xTg mice

Eleonora Daini, Eleonora Vandini, Martina Bodria, Wenjie Liao, Carlo Baraldi, Valentina Secco, Alessandra Ottani, Michele Zoli, Daniela Giuliani, Antonietta Vilella

Summary: Alzheimer's disease (AD) is the most frequent cause of dementia and lacks effective therapy. Previous studies have shown that treatment with melanocortin analogs can induce neuroprotection in the early stages of AD. In this study, the neuroprotective role of melanocortins was investigated in two transgenic mouse models of severe AD. After 50 days of treatment, it was found that chronic stimulation of melanocortin receptors improved cognitive abilities of AD mice and decreased levels of hyperphosphorylated Tau, but had no effect on Aβ burden.

Influence of tall buildings on city-scale seismic response analysis: A case study of Shanghai CBD

Yuan Tian, Siying Chen, Simeng Liu, Xinzheng Lu

Summary: Tall buildings have a significant impact on the seismic safety of shorter buildings in their surroundings. Previous studies have mainly focused on analyzing the structure-soil-structure interactions in the local vicinity. However, considering the mass and period of tall buildings, their influence during earthquakes can extend over a wide area. Therefore, it is crucial to investigate the influence of tall buildings from a city-scale perspective.

M. I. Nizovtsev, A. N. Sterlyagov

Summary: The effect of adding a layer of phase change material on the thermal inertia properties of the outer wall in lightweight building was numerically studied. It was found that in the regime of indoor air conditioning, adding a layer of paraffin in a foamed polyurethane wall can significantly reduce heat flux fluctuations on the inner wall surface. Additionally, locating the phase change material on the inner surface of the wall in the regime of daily in-phase fluctuations in the indoor and outdoor air temperatures produces the best effect.

Applicability of a dedicated outdoor air system assisted by isothermal dehumidification and evaporative cooling

Seong-Yong Cheon, Hye-Jin Cho, Jae-Weon Jeong

Summary: A dedicated outdoor air system (DOAS) assisted by an isothermal dehumidifier and an indirect evaporative cooler is proposed, and its energy-saving potential is evaluated based on detailed simulations. The results indicate that despite the free cooling operation by the indirect evaporative cooler, the proposed system consumes 10% more operating energy due to the low coefficient of performance (COP) of the isothermal dehumidifier. Improvements in the COP of the isothermal dehumidifier are required for comparable energy performance.

Experimental investigation on the compressive behavior of rat-trap bond wall strengthened with steel plate frame under preload

Haoran Cheng, Denghu Jing

Summary: This study investigated the reinforcement and compressive behavior of rat-trap bond walls using steel plate frames. The results showed that the steel plate frame effectively enhanced the compressive peak load of the wall, and increasing the steel plate thickness improved compressive strength and confinement effect. Nonlinear relations were observed between the preload ratio and the peak load, and local buckling of the steel plate frame was affected by the preload ratio. Finite element models were used to verify the experimental results, and calculation formulas for predicting the compressive peak load were developed and found to be accurate.

Experiment and finite element modelling on compressive and damage evolution of graphene nanoplatelet reinforced Porous cement composites

Bangyu Cheng, Jinlong Yang, Yucheng Fan, Zhi Ni, Ziyan Hang, Bowen Zeng, Huanxun Liu, Chuang Feng

Summary: This study investigates the property-microstructure relationships in graphene nanoplatelet (GNP) reinforced cement composites (GNPRCCs) using three-dimensional finite element modeling and experiments. The results reveal that GNPs aligned at 45 degrees have the most significant impact on enhancing load-bearing capacity and damage resistance of the composites. A larger GNP diameter-to-thickness ratio is beneficial for crack bridging and propagation control. The orientation and porosity of pores have significant effects on the damage behaviors of the composites, while pore shape shows negligible effects. These findings provide key guidelines for optimizing microstructural features and improving the performance and durability of construction materials.
