Published: August 2020

Abstract
The advancement of technology has changed the function and structure of the building space. The prefabricated steel structure is in a period of vigorous development, which is an important way for the development of industrialization of buildings. Therefore, the key technology of prefabricated assembled steel structure is a key problem that needs to be solved urgently. It is particularly important in the optimization and upgrading of the form of the building structure. At the same time, the design and construction of the beam-column connection node is also crucial, which directly affects the construction process and speed. In this paper, a new type of assembled steel structure beam-column joint is designed, and the seismic behavior of the structure is analyzed through experiments. Experiments show that the structure has good seismic behavior, which not only effectively solves the problem of structural interference, but also reduces the construction process and improves the construction speed.
Analysis of Mechanical Properties of Polymer Matrix Composites
Authors: Zhang WX , Yang LM 
Published: August 2020

Abstract
Polymer materials have obvious viscoelastic properties. Viscoelastic mechanics mainly studies the relationship between deformation and external force, load time, load rate and other factors under the influence of external factors, as well as the stress field, strain field and relevant laws in the object. The deformation of viscoelastic materials is strongly dependent on time and temperature. The viscoelasticity of the material will change with the temperature. If there is no obvious creep at room temperature, there will be significant deformation and flow at higher temperature, and even the phenomenon of material failure will be different. If the temperature changes too much, it will change the mechanical properties of the material.

Published: August 2020

Abstract
When the temperature changes, the stress produced by the external constraint and the mutual constraint between the internal parts of the object, which makes it unable to expand and contract freely, is called thermal stress. The thermal stress is caused by the steady temperature field. When the transient temperature changes to zero and the temperature distribution reaches a stable state, the temperature distribution can be obtained from the heat conduction equation and temperature boundary conditions, and then the displacement and stress can be obtained from the elastic equation including the temperature term.

Published: August 2020

Abstract
The reasonable determination of pile spacing is an important link in the design of anti-slide pile. At present, there are many research results on the calculation method of maximum pile spacing of anti-slide pile. Due to different assumptions, different angles of analysis, and different complexity of the formula, the calculation results are quite different, and the research results have not been widely popularized. In this study, taking into account the whole soil arching as the research object, the formulas for calculating the maximum pile spacing of the anti-slide pile based on the soil arching effect behind piles or between piles are put forward considering the overall mechanical balance condition and strength condition of the soil arching, and its rationality is verified by an engineering example. Through calculation and analysis, it is considered that the soil arching between piles controls the maximum pile spacing of anti-slide pile. Through the comparison and analysis with the previous research, the results showed that the calculation formula in this paper is reasonable, feasible and simple, and is convenient for popularization and application in actual engineering.

Authors: Dong Qian 
Published: August 2020

Abstract
It is of great importance to study the proper rock blasting damage constitutive model for the design of rock blasting excavation parameters and the damage assessment of retained rock. Therefore, on the basis of the classic KUS rock damage constitutive model which only involved tensile damage, considering the compression-shear damage of rock near the explosion source caused by extensive blasting load, an improved rock blasting damage constitutive model is established. Meanwhile, the distribution of rock damage zone of a single blasthole is calculated by dynamic finite element software based on the improved model, and the results show that the ratio of crushing zone radius to cartridge radius is between 4.3 and 4.6 under different charging radius, while the ratio of fracture zone radius to cartridge radius is between 78.9 and 83.8, which is close to the existing research results. Thus, the accuracy of the established constitutive model of rock blasting damage is verified.

Authors: He Chuankai 
Published: August 2020

Abstract
The navigable clearance scale is a key factor in the selection of bridge type schemes on urban navigable rivers, especially in the case of limited clearance, the restriction of pier size and shape on navigation. In this paper, the impact of different pier structures on navigable flow is analyzed through the two-dimensional flow mathematical model simulation of new bridge section of a river. The results show that the shape optimization of square pier chamfer can reduce the transverse velocity of navigable flow; and the larger size of pier, the greater transverse velocity of navigable waters. Furthermore, the transverse velocity of the navigable flow is the smallest on the condition of the same width but round form of head pier structure. The new design can effectively solve the contradiction between bridge navigation and landscape construction on urban navigable river, and provide a variety of options for bridge construction.

Abstract
Prefabricated building is the new construction method of technical reform and upgrading in China’s construction industry. The construction of prefabricated buildings involves the production, transportation and hoisting of large prefabricated components. Due to the difficulty in handling large prefabricated components, lacking of prefabricated building construction experience of workers, insufficient management guidelines for prefabricated building, there are a large number of hazard sources in the new production environment. This paper is to identify hazard sources relating to prefabricated components which exist in four stages of production, transportation, on-site storage, and installation. Firstly, we used the method of literature study to initially identify the hazard sources of prefabricated buildings; then, expert investigation was applied and Entropy Weight Method was used to evaluate the severity of hazard sources; finally, significant hazard sources at each stage were identified and countermeasures were put forward for the prevention of accidence. This study enriches the theoretical research on prefabricated building safety management and provides references for the prevention of prefabricated building safety risks.

Abstract
Fissure density is an important evaluation indicator of the degree of fissure development for fissure soils, which is not easily measured by traditional methods. A new statistical method based on Visual Basic programming was proposed to calculate fissure density. The basic principle of this method is to convert colour pixels into black-white pixels based on brightness calculation, and then calculate the fissure density according to the proportion of black-white pixels. Through the above methods, the statistics of the fissure density and fissure area of shrinkage soil sample can be realized.
