Published: April 2023

Abstract
In order to help architects Reduce energy consumption in buildings more pertinently in the early stage of design, this paper takes high-rise hotels in Guangdong as a research subject, obtains the building characteristic factor data of 28 groups of hotel samples through investigation, successively models and simulates the energy consumption value in Energy Plus software, and then studies the energy consumption characteristics and influencing factors of hotel buildings in Guangdong through the simulation results. Results show that the plane type has little effect on the energy consumption per unit area, and the standard floor area, the standard floor height and the four-way window wall ratio have a greater impact on the total energy consumption of the building. Except for the standard floor area, other building characteristics have a positive correlation with the total energy consumption per unit area.

Abstract
The Beijing-Tianjin-Hebei region, one of the most serious areas of ground subsidence in China, has entered the stage of high-speed development of synergistic integration, and the establishment of a unified and efficient, automatic and intelligent, mature and advanced monitoring and warning prevention system is inevitable.

Abstract
The identification on the mechanical characteristic of walking leg has faced challenge due to the inconvenience installation on sensor with leg and expensive cost. This paper proposes a convenience method on identifying the leg parameters including its stiffness and damping ratio under walking state by Extend Kalman Filter (EKF) method, which only need to deal with the measured ground reaction force. Firstly, a mechanical oscillate system is used to describe the walking leg, and its corresponding dynamic governing equation is established. Then, a state-space equation is applied the governing equation and it is further inserted on the EKF method so as to set up a system update equation and measurement update equation. In addition, a solving algorithm is designed to acquire the instantaneous stiffness and damping ratio of the walking leg. Finally, a sample comprised of 760 curves of walking ground reaction force from 36 participants is employed to the identification method and the practice results demonstrate that it can efficiently discern the stiffness and damping ratio of walking leg. This study provides a novel perspective for seeking the dynamic parameters of walking leg and efficiently reduces experimental expenditure than those direct measurement of sensors installed on the surface of leg.

Published: April 2023

Abstract
Effects of water layers of different thickness and different frequencies of sound for sound transmission intensity have been analyzed by calculations of sound waves propagating in air and water layer. The results have showed that, when water layer thickness is less than 5mm, the changes of thickness have a powerful effect on sound waves, while it is more than 5mm, there is nearly no effect with different thickness, however, frequency of sound waves play a decisive role, especially when the sound wave frequency is less than 100Hz.

Authors: Wang Jiancheng , Song Yanhng , Huang Ning 
Published: April 2023

Abstract
A field observation along the Hetian-Ruoqiang Railway (HRR) was carried out from July 2021 to January 2022. The spatial characteristic of wind-blown sand is subsequently obtained. For the wind field, the results show that the northeasterly wind is mainly prevalent from Ruoqiang to Qiemo during the monitoring period. The northwestly wind is mainly prevailing from Hetian to Yutian. Around Minfeng, northeasterly wind from Ruoqiang and northwesterly wind from Hetian form an airflow convergence zone here. The cumulated aeolian transport mass flux Fcm in the east section from Ruoqiang to Qiemo is larger, but a typical sand-transport spoke center arises near the right flank of Minfeng, resulting in a large Fcm in this area. These results have engineering significance for the prevention and control on wind-sand disasters along HRR.

Published: April 2023

Abstract
Large and complex bridges usually have significant nonlinear effects. In the design of seismic and other dynamic characteristics, it is usually impossible to obtain results from simple force calculations. In this paper, taking the mechanical parameters of the complex structure of double wide double tower cable-stayed bridge as an example, a shear damper in seismic field is designed. The experimental results show that: (1) The shear type mild steel damper can improve the lateral seismic performance of cable-stayed bridges. (2) Because the double span cable-stayed bridge is connected by dampers between towers, the mechanical parameters of dampers will affect the natural structure of the bridge, and there is no obvious linear relationship between the yield force of the damper and the bending moment at the bottom of the tower.

Authors: Sun Y J , Shi D W , Guo J 
Published: April 2023

Abstract
Steel is the most basic raw material in China’s industrial production, which plays a great role in promoting China’s industrialization process. Therefore, it is of great significance to detect defective steel and the surface quality of steel. In order to further improve the detection accuracy of steel surface defects, this paper proposes a steel surface defect detection algorithm based on global context block. In this paper, a global context module is introduced based on the UNet++ network model to achieve accurate segmentation and classification of complex steel surface defects. The results show that the improved UNet++ network model achieves a dice coefficient of 94.67% on the steel surface defect dataset provided by the Kaggle competition platform. Compared with semantic segmentation models such as UNet, LinkNet, and UNet++, the segmentation effect is more accurate. Therefore, the deep learning model based on the improved UNet++ can learn more semantic features from industrial steel images, so as to obtain more accurate steel defect information. This method can be a big help for real-world applications like defect detection in industrial images.

Secondly, the principle of the depth self encoder is analyzed, and the pulse signal after the short time Fourier transform processing is input into the depth self encoder. Finally, according to the distance function, the gradient descent algorithm is used to update the parameters. Through iterative calculation, the detection of low frequency pulse signal of LSI is completed. The experimental results show that, compared with the traditional low-frequency pulse signal detection method, the detection accuracy of this method is greatly improved, up to 99.79%, and can shorten the overall detection time.

The analysis results show that the reinforcement arranged in the diaphragm can significantly improve the ultimate bearing capacity of the overall structure by welding with the diaphragm, effectively improve the stress distribution of the bolt, reduce the stress value of the connection between the bolt and the steel plate, and improve the shear resistance of the bolt. With the wide application of corrugated steel webs, more attention should be paid to the force transmission performance of the connection interface between the steel webs and the concrete diaphragm in the engineering design process. The research results can be used for the design calculation of the connection between the corrugated steel web composite beam bridge and the diaphragm in the future, and provide reference for engineering application.
