“…Moreover, the role of operation temperature on the primary physical property parameters was considered in this work. The functions of these parameters with temperature are described as follows [ 36–38 ] :

D_{m} goodbreak= D_{m, 0} {(\frac{T}{T_{0}})}^{1.75},

K goodbreak= K_{0} italicexp ((), \frac{- italicΔH}{RT} goodbreak+ \frac{ΔH}{R T_{0}}),

According to the actual operating conditions of the combined electrothermal regeneration processes, the macroscopic boundary conditions of this numerical study are listed in Table 4, where P 0 denotes the constant atmospheric pressure at the outlet. In addition, at the initial time (i.e., Fo = 0), the ACF felt has a uniform temperature (i.e., T 0 = 293 K), and the initial residual concentration of toluene in macroscopic pores of ACF felt is defined as C 0,t = 1 g/m 3 .…”

Porous activated carbon fibre (ACF) materials, as a recycled absorbent, have been widely applied in the harmless disposal of volatile organic chemicals (VOCs). In order to reduce the energy consumption of cyclic regeneration process and avoid second pollution of high concentration VOCs, there is an urgent need to develop a synergistic regeneration method to recover the adsorptive capacity of ACF and achieve the in‐situ degradation of VOCs simultaneously. Due to the outstanding oxidation performance of ozone, ozonization was used to degrade VOCs adsorbed by absorbent materials and has a potential advantage in combination with the traditional electrothermal desorption technology. In this work, a three‐dimensional pore‐scale lattice Boltzmann method (LBM) is established to solve the convective heat and mass transfer processes considering the desorption and ozonization effects. Using this numerical model, a pore‐scale simulation is performed to investigate the reactive and desorptive transport behaviours in the reconstructed pore structure of ACF felt, which is regenerated using the electrothermal desorption process combined with the ozonization degradation method. The simulation works reveal the effects of key operation parameters on the desorption and degradation mechanisms into the pores of ACF felt during this combined regeneration process. The numerical results show that the flow velocity of carrier gas plays an important role on the performance of the combined regeneration process. The approach of reducing the carrier gas velocity would obviously improve the degradation ratio of VOC and the efficiency of the combined regeneration process.

It has been found that in the event of a strong earthquake, and due to insufficient distance between two adjacent structures, the lateral movement at the top of structures may cause collisions between them. This phenomenon, commonly known as seismic collision, can generate impact forces that were not considered during the initial design of the structure. These forces can cause significant structural damage or lead to complete collapse of the structure. The main purpose of this paper is to study the coupled effects of soil flexibility and impact between adjacent buildings undergoing seismic excitation. To capture the impact forces between the structures during the collision, a modified linear viscoelastic model was used effectively. Particular attention has been paid to studying the effects of shear wave velocity, first on the soil structure interaction and then on the collision response of adjacent structures. Three configurations of adjacent structures were analyzed: light-light, light-heavy, and heavy-heavy structures. The results obtained through this analysis showed that the dynamic response and the impact force of the structures depend essentially on the interaction between the structure, the foundation, and the soil.

Bamboo, as a green building material, plays a vital role in construction. Bamboo has good properties and appearance, making it highly attractive for building structures and designs. Since the compressive capacity of bamboo is considerably lower than its tensile capacity, with the ratio typically ranging between 300% to 900%, this limits its application dimensions in construction. Therefore, filling the original bamboo structural members with specific materials or applying different connection methods can not only maintain the appearance of the bamboo structure but also improve its compressive capacity and overall durability, thus expanding the application range of bamboo structural members and enhancing the performance of the architectural design process. Two hollow bamboo specimens were among the eight BFC specimens tested for this paper. Key components such as transverse stiffeners, steel bars, filler materials, and bamboo nodes were examined for their influence on the specimens’ ductility, peak strain, ultimate bearing capacity, and failure mechanisms. The test results showed that the ratio of the ultimate bearing capacity of BFC specimens to hollow bamboo samples could reach up to 538%, while the peak strain differences were minimal. A non-linear finite element model was developed and its accuracy confirmed based on the test results. This work proposes a new approach to determine the final axial compressive capacity of BFC columns by creating an elastic model of transversely isotropic cylinders. As a result, the primary goal of this study is to establish a foundation for more scientific building design techniques and procedures by examining the axial compression mechanics of structural bamboo filled with cement and concrete (BFC) and how it influences building design.
