Authors: Cheng Hu , Weng Xingzhong 
Published: September 2020

Abstract
Prevention and control of cement concrete early micro cracks is currently one of the highlights in agro-scientific research of the airport engineering. Early micro cracks are mainly produced in concrete surface mortar layer, so reinforcement effect of fiber mesh with three types and three mesh size was studied by mortar flat test. The results show that cement mortar early crack resistance is greatly improved by fiber mesh. Fiber mesh type and mesh size have a great influence on cement mortar early cracking resistance. Specifically, aramid fiber mesh enhancement effect is better than that of basalt fiber mesh and better than that of carbon fiber mesh. At the same time, 3*3mm basalt fiber mesh enhancement effect is better than that of 5*5mm and is better than that of 10*10mm. Compared with control group, total cracking area per unit area of 5*5mm basalt fiber mesh decreases by 92.5%, and its crack reduction coefficient reaches 66.6%. Considering both cost and enhancement, 5*5mm basalt fiber mesh is recommended for engineering.

Prediction model of ground vibration based on combined model
Authors: Hong Zhao , Jing Zheng , Fulian Yang , Ming Zhou , Can Xiong 
Published: September 2020

Abstract
The two basic functions of power function and exponential function are used, and the variable weight combination model based on the Lagrange multiplier of the two basic functions is used to predict the surface vibration attenuation. Based on the measured data of the ground surface vibration of viaducts and embankments, a prediction model can be established through a combination model. A better fitting effect can be acquired through this prediction model. The model can obtain better prediction with fewer parameters and can comprehensively reflect the different model information of the two models. Although the amount of data is limited, it can also be obtained. The predictions that are in good agreement with the actual situation are better, the vibration attenuation in the near field is faster, and the vibration attenuation in the far field is slow, which are consistent with the actual situation.

Abstract
The dynamic splitting tensile tests of five kinds of concrete with different content of carbon nanofibers were carried out by split Hopkinson pressure bar (SHPB) device. The dynamic splitting tensile mechanical properties of carbon nanofibers reinforced concrete (CNFC) are analyzed in terms of the relationships between the stress-time curve, dynamic splitting tensile strength, dynamic splitting tensile increase factor (DTF) and the content of carbon nanofibers as well as strain rate. The results show that: the dynamic splitting tensile strength of concrete is enhanced by carbon nanofibers; at the same strain rate level, with the increase of the content of carbon nanofibers, the dynamic splitting tensile strength of concrete shows a trend of first increasing and then decreasing; when the content of carbon nanofibers is the same, as the strain rate increases, the dynamic splitting tensile strength of concrete continues to increase.

CFST arch bridge seismic response analysis considering near-fault ground motion pulse characteristics
Authors: Fan Xing , Xiaofeng Li 
Published: September 2020

Abstract
Based on a long-span CFST arch bridge finite element model, nonlinear time-history response analysis is carried out. It is found that the key section of the connection of arch rib and bridge deck is a particular location with larger seismic response. The fling-step type TCU068-E is more liable to excite a greater seismic response at arch rib sections. Through seismic wave dyadic wavelet analysis, the wavelet component in the structure fundamental frequency band is reconstructed to be a new seismic excitation. The results indicate that the low-frequency component of TCU068-E is strong, and larger structural seismic response is generated accordingly.

Authors: Wei Yinshang , Cui Enwei 
Published: September 2020

Abstract
In the traditional data management of safety information for construction workers, each department independently manages and uploads data. It is difficult to share data and the utilization rate of worker safety information is low. In response to this problem, a safety information management model for construction workers based on blockchain and big data technology is proposed. This model is based on the characteristics of the blockchain to record data, which completely changes the data collection, data processing and analysis, and data storage modes and methods, and records the entire process of safety-related data and information of construction employees during their work. Build a complete personal safety information chain, which truly reflects the safety literacy of employees, and establish a safety quality information storage evaluation system for coal mine employees. This model can provide real and effective safety information for construction safety management and promote personnel matching.

Authors: Liu Lijun , Zhang Wenfang 
Published: September 2020

Abstract
In order to study the influence of different design response spectra on the internal force of the isolated structure, the response spectra of the “Code for Seismic Design of Buildings” (Abbreviated as SD), the response spectra of “Design Standards for Seismic Isolation of Buildings” (draft for comments)(Abbreviated as ID) and the response spectra based on pseudo acceleration calibration(Abbreviated as PA) are analyzed. Compared with SD response spectra, ID response spectra adopts the (1/T) attenuation mode in the long period, which reduces the value of the earthquake influence coefficient in the long period of the response spectrum. At the same time, there is no overshoot phenomenon in ID response spectra. This paper presents the response spectrum basic on structural elastic displacement. PA response spectra considers the influence of different sites on the long-period structure, and adds the characteristic period corresponding to different sites. The calculation shows that compared with the calculation result of SD response spectra, the floor shear force calculated by ID is reduced, and the reduction ratio is between 31% and 36%. Compared with the floor shear force obtained by using PA response spectra, the reduction ratio is between 19% and 29%.

Abstract
In order to study the seismic performance of ancient timber structures under different earthquake intensities, this paper uses the finite element software ABAQUS to establish a finite element model. Through the incremental dynamic analysis (IDA) of the model under the action of two-way horizontal earthquake, IDA curves of multiple ground motion records are obtained, and the IDA curves of 16%, 50%, and 84% ratio are calculated. Combined with the earthquake vulnerability theory, the earthquake vulnerability matrix is established to evaluate the seismic resistance of the ancient timber structures. It provides a reference for the future anti-seismic research of ancient buildings, and also provides an effective way for timber structure anti-seismic safety evaluation.
Improving the distribution uniformity of surface hardness of the cured CFRP molniezaschita coating during processing in a microwave field elektromagnitnom
Authors: Zlobina I V 
Published: September 2020

Abstract
In the structural elements of advanced air transport and wind turbines are widely used fiber-reinforced polymer composite materials: carbon and fiberglass. In order to increase the resistance of materials to static electricity and lightning discharges, lightning-proof coatings are included in the structure of the polymer composite materials. In the process of operation, there may be collisions of the plumage and planes of aircraft, as well as large-sized blades of wind turbines with solid objects. Therefore, along with the strength and resistance to high-amplitude low-cycle loads, one of the important characteristics of polymer composite materials that determine their performance properties is hardness. Strength and endurance of polymer composite materials products can be increased by short-term exposure to microwave electromagnetic field. The presence of a built-in metal structure introduces additional uncertainty in the perception of anisotropic polymer composite materials operating loads, as well as in the process of interaction with the electromagnetic field of ultrahigh frequency. The studies of the hardness distribution on the surface of carbon plastics with built-in lightning-proof coatings under different schemes of exposure to microwave electromagnetic field: from the lightning-proof coatings, from the side opposite to the lightning-proof coatings, sequential processing on both sides compared with the starting material. It is found that processing in a microwave electromagnetic field with an energy flux density (17-18) ×104 mW/cm2 for 2 minutes leads to a significant increase in the uniformity of the initial hardness of the surface of the samples.

A physical model of the interaction of microwave electromagnetic fields with the cured polymeric composite materials with distributed in volume of metal structures
Authors: Zlobina I V 
Published: September 2020

Abstract
The paper shows the results of experimental studies of the short-term effects of microwave electromagnetic field on the physical and mechanical properties of cured polymer composite materials, including distributed in the volume of metal elements such as lightning protection grids and cellular structures. It is stated that as a result of processing in a microwave electromagnetic field with a frequency of 2450 MHz with an energy flux density (EFD) (17-18) ×104 mkW/cm2, the microstructure is modified, which consists in reducing the porosity and pore size in the matrix, reducing the size of agglomerates and increasing their number. The change in the content of the main chemical elements in the contact area “reinforcing fiber-matrix” and “metal structure-matrix” was noted. The main practical result of the impact of microwave electromagnetic field on the final product is a significant increase in static and dynamic strength, including the limit of low-cycle fatigue, modulus of elasticity and crack resistance. This physical model can be used as a basis for mathematical dependencies that allow to predict the strength of the adhesion interaction between the matrix and the filler in the polymer composite materials by calculation, taking into account the density of the microwave energy flow incident on the surface of the cured product and stimulating diffusion processes in the contact zones “matrix-fiber”.
