Based on the non-inertial reference system, the vehicle model of four freedom degrees is used to establish the vehicle-bridge coupling dynamic system model of the curved beam in space. Considering the vehicle-bridge coupling vibration characteristics under the non-uniform seismic excitation at the two supports of the bridge, the three-dimension space curvilinear-vehicle coupling dynamic control equation is established based on the Hamiltonian principle. Then the coupling dynamic control equation of the vehicle and bridge is numerically analyzed by the method of separating variables.

Slag is a fine-grained glassy material formed from molten slag of blast furnace when it is quenched, and it is kind of active admixture. Therefore, the slag as admixtures mixed into cement based materials, whose activity can play a important role in the hydration reaction and improve the mechanical properties of cement based materials. In this paper, the influence of the kinetics of hydration of slag and cement was analyzed, and the dynamics equation of the hydration of slag Portland cement system was established. The influence of slag on slag Portland cement system hydration process was analyzed mainly from the water binder ratio,temperature and the ratio of the influence of slag on slag Portland cement system hydration process. The results show that, the increasing of water binder ratio, temperature increasing and the cement particle specific surface area increasing can accelerate the hydration process of slag Portland cement system in different degree.

In this study, the KOH-modified Fe-ZIF-derived carbon materials (Fe@NC-KOH-x) were designed for Fenton-like systems to enhance bisphenol A (BPA) removal from wastewater. Compared with the Fe@NC without KOH activation, the pore structure, BET (Brunner-Emmet-Teller) surface area, and oxygen-containing functional group of KOH-activated Fe@NC-KOH-x are dramatically improved, which increases the adsorption and catalytic performance. The Fe@NC-KOH-900/PMS system showed significant BPA removal reactivity across wide pH ranges and low doses of Fe@NC-KOH-900. Interestingly, our findings indicated that the removal effectiveness of BPA improved when PMS was introduced following the saturation adsorption of Fe@NC-KOH-x, as compared to the simultaneous introduction of Fe@NC-KOH-x and PMS. More particularly, through regression analysis, we found that the proportion of reactive species in the Fe@NC-KOH-x/PMS system changes with the increase of pyrolysis temperature, and there was a certain relationship between structure–function and active species in the Fe@NC-KOH-x/PMS system. O-C = O, Fe-N4, C-O, and pyrrolic N in Fe@NC-KOH-x lead to the generation of •OH, and SO4−•, C = O, Fe-N4, and defect are closely related to FeIV = O, and the formation of 1O2 is affected by Fe-N4, graphite N, C = O, and defect. Also, the density functional theory (DFT) calculation and the potential correlation between catalyst active centers and reactive oxygen species indicate that Fe-N4 is the main active site of Fe@NC-KOH-x. These outcomes of the study offer an innovation for enhanced elimination of BPA in wastewater treatment and provide a dynamic understanding of the mechanism of BPA degradation. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.

With the development and progress of the social sciences, the Party and the state have attached great importance to the work of the construction of the informatization. Especially the Eighteenth National Congress of the CPC put forward the synchronous development of the ＂four modernizations＂, and promoted the information technology to the national strategy, making the field of the construction of the informatization broader, so that the informatization also occupied an important position in the construction of colleges and universities. The development of the informatization plays an important role in the development of colleges and universities.

Pressure vessel is a kind of special equipment which is involved in various industries. Once it is damaged, it will cause great loss to people's life and property. The traditional elastic modulus reduction method for upper bound limit analysis of pressure vessels adopts the elastic-perfectly plastic material model. This method will result in waste of materials without considering the material strain hardening effect. So the material strain hardening effect is introduced into upper bound limit analysis. Firstly, the equivalent yield strength considering material strain hardening effect is established. Then, the formula of limit load multiplier which is expressed by the equivalent yield strength is derived based on the upper bound theorem. Combined with the strategy for elastic modulus adjustment, the elastic modulus reduction method for upper bound limit analysis of pressure vessels incorporating material strain hardening effect is constructed. The limitation of the elastic-perfectly plastic model for the upper bound analysis method is eliminated by the method proposed in this paper. The result calculated by this method is closer to the true limit load of pressure vessels. © 2021 Institute of Physics Publishing. All rights reserved.

Effects of special environment on the basic mechanical properties of Carbon fiber (CFRP) anchor were studied by acidic, alkali, salt solutions and tensile test. Using of bond stress and slip linear regression method to forecast the slip value of different reinforcement diameter, different anchoring length under general environmental and acidic, alkali, salt solutions corrosion. Test and analysis results show that the tensile strength of CFRP and Epoxy mortar changes, the elastic modulus, elongation change little, the bond slip amount increased by more than 50%, bond performance relative to influence by the corrosion. With acid, salt corrosion as compared to a case, the bonding properties of CFRP anchor and epoxy mortar are more sensitive to alkali corrosion. © 2015 Taylor & Francis Group, London.

To study the effect of dynamic load on the energy dissipation mechanism of red sandstone soil under different dry densities, it is of great significance to improve construction quaity and progress. The cyclic impact test of red sandstone soil under different dry densities was carried out by the SHPB test device, and the effect of dry density on its energy dissipation was analyzed. The results showed that with the increase of the number of impacts, the energy dissipation density of the specimen increases first and then develops gently. The cumulative energy dissipation density increases with the increase of the number of impacts, and the larger the dry density, the greater the cumulative energy dissipation density. According to the energy ratio analysis, only about 28% of the energy is used for the reinforcement of the specimen, and most of the energy is in the form of transmission energy and reflection energy. © 2020 ISRM.
