Authors: Kaur Manpreet , Aggarwal S K 
Published: November 2020

Abstract
Pavement design on weak subgrade soils is to a certain extent challengeable and challenging for transportation and geotechnical engineers. Weak soil is vastly compressible clayey soils so the life of the pavements is less and effect of the weakening of the paved or unpaved surface. The development of such soil are substitutes such as replacement and excavation of unsuitable soils, compaction, Mechanical and chemical stabilization, Pre-compression and reinforcement of soil, etc., are used typically at such locations. During the recent historical utilization of reinforcement of soil by various methods has been increased to progress the strength properties and bearing capacity of poor subgrades. Field signals indicate that geosynthetic reinforcements will expand pavement performance. From this, the employment of various geosynthetics to pavement surface is testified by several researchers. Geosynthetics has numerous applications such as separation, reinforcement, filtration, drainage, and containment, etc. This paper targets to study the conclusions from various studies on weak subgrade soils using reinforcement.

Authors: Pan Futing , Wang Ying , Huang Chunxiao , Zhang Li 
Published: November 2020

Abstract
Steel-timber composite member is a new kind of structural member composed of steel plates and planks which are connected by bolts. The finite element analysis results on the flexural behavior of steel-timber composite centilever beam show that the stress of steel plate exceeds the yield strength before the bearing capacity of the composite beam is lost. Under the premise of ensuring the yield of the steel plate, the increase in the thickness of plank has little effect on the in-plane bending stiffness of composite beam, and the lateral bending stiffness of the composite beam is obviously improved which means the plank can effectively restrain the lateral buckling of the core steel plate. Based on the deflection analysis of composite beams, the deflection coefficient of steel-timber composite is derived.

Published: November 2020

Abstract
Predicting the change of runoff in the future is significant to the management of regional water resources. In order to estimate future climate change of Ganjiang river basin and explore its impact on runoff, the changes of precipitation and temperature under the three representative concentration pathways (RCP2.6, RCP4.5 and RCP8.5) were analyzed and the Soil and Water Assessment Tool (SWAT) hydrological model was established to simulate the corresponding runoff in the Basin. The statistical relationship between the factors and the predictor in the Ganjiang river basin was built based on Statistical Downscaling Model (SDSM). For three scenarios, the precipitation showed slight increase trends under RCP2.6 and RCP4.5, but a significant increase under RCP8.5; and generally decreased from July to October while increased from January to April. The temperature exhibited a rising trend under three scenarios, of which the rank was RCP8.5>RCP4.5>RCP2.6. The runoff had an increasing trend and the rank for the three scenarios was RCP8.5>RCP4.5>RCP2.6. Generally, runoff had a strong positive correlation with precipitation while a weak correlation with temperature. The flood risk in Ganjiang river may increase significantly in the future.

Published: November 2020

Abstract
The prefabricated structure is vigorously promoted due to its obvious superiorities of high-efficiency construction rate and environment-friendly construction scheme. However, this fast-growing new structural system is still facing the threat of earthquakes, especially its beam-to-column connecting joints which are the weaker link in the entire structural system all the time. This study investigates the failure behaviour of hole-opened metallic plate connections in prefabricated energy-dissipation joints and its finite element models were provided. Parametric study was performed to obtain the influence of metallic-plate size on the bearing capacity, deformation performance, and ductility. Based on the results of numerical simulation, the failure modes of specimens were focused on weakened sections. Moreover, proposed design sizes were given, comprising that the weakened length a/L of holes is from 0.25 to 0.55 and the weakened width b/B is from 0.3 to 0.5. The suggested value of width to thickness ratio is 0.2 and the value of the gap is within 0.5 to 2 mm.

Abstract
In order to better coordinate the structural performance with lightweight goal, multi-stage lightweight strategy based on structural performance influence analysis is proposed. The framework of knowledge-guided lightweight design with multiple behavior routes was constructed firstly. Some behavior routes, such as initial structural design, lightweight optimization combined with structural performance influence analysis and knowledge-guided lightweight optimization, were designed in this section. Secondly, the decomposition of decision task and the multi-stage lightweight decision based on structural performance influence knowledge were discussed. Finally, the palletizing manipulator with parallelogram leveling mechanism was taken as an example to apply proposed strategy. Comparing with the initial optimization model in the first stage, the total weight of the components after multi-stage lightweight has been reduced by 23.37%, but the maximum stress of total manipulator only increased by 10.3Mpa, which shows the significant effect of lightweight.

Published: November 2020

Abstract
Polyurethane acrylate modified epoxy acrylate resin with high solid content and great mechanical properties was synthesized by addition of polyethylene glycol in this work. The conversion process from liquid to solid was confirmed by comparing the FT-IR of oligomer and film. The disappearance of the carbon-carbon double bond absorption peaks at 1639 cm−1 and 819 cm−1 indicates that the oligomer is cured completely. In addition, the thermal analysis of the resin was characterized by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). According to the experimental data, it can be seen from that the resin started to decompose at 293.31 until it is almost completely decomposed at 481.73°C which indicated that the stability of the film was better and the decomposition temperature was higher. In addition: Compared with the thermosetting resin E51 and the modified resin, the glass transition temperature is reduced by about 31 °C, which solves the problem of brittleness and hardness.

Published: November 2020

Abstract
Structure and material are the two key factors affecting the jet forming of the liner. To investigate the influence of new structure and new materials on the jet forming of the liner, a shaped charge model with eccentric sub-hemisphere structure based on ZrCuNiAlAg amorphous energetic alloy was proposed. The jet forming law of eccentric sub-hemispherical liner is studied by fixing other parameters and changing the structure parameters of liner in turn by means of AUTODYN numerical simulation software. The simulation results show that the eccentric sub-hemispherical liner of ZrCuNiAlAg amorphous alloy can form a shaped jet very well by using gathering energy effect. The speed of the shaped jet decreases gradually with time, and the shape of the jet changes from short and thick to long and thin. The curvature radius, eccentricity and wall thickness have a significant effect on the jet forming performance of ZrCuNiAlAg amorphous alloy. As the curvature radius or wall thickness increase, the tip velocity and the length diameter ratio (LDR) of the jet will decrease gradually, while with the increase of the eccentricity of the liner, the jet tip velocity and the LDR will increase gradually. The analysis of simulation data shows that the change of eccentricity has the greatest influence on the jet LDR. When the eccentricity increases from 25 mm to 39 mm, the jet LDR increases by 74% at 60μs. The wall thickness has the greatest influence on the tip velocity of the jet. When the wall thickness increases from 1.4 mm to 3.8 mm, the tip velocity of the jet at 60μs decreases by 29.77%. The results of this paper can be used for scientific reference in the structural design of this kind of liner.

Published: November 2020

Abstract
In this research, the abnormal magnetic signals were detected in dynamic tension tests on the ferromagnetic material specimens, in order to study the characterization method of abnormal magnetic signals for the crack propagation life. It is indicated that fatigue crack length a is linear with the peak-peak value ΔHpa(y) of abnormal magnetic signals. The ΔHpa(y) of fatigue crack and the gradient of magnetic field intensity k increase with the increase of fatigue cycle number. Therefore, ΔHpa(y) and k are confirmed as the key parameters of characterizing crack propagation life. Then, a life prediction model of abnormal magnetic signals for the crack propagation life is founded based on the Paris equation. The maximum error between measured values and calculated values is less than 15%.

Published: November 2020

Abstract
It is difficult to obtain reliable shear strength parameters for the stability analysis and evaluation of high loess slopes. Hence, this paper determines 17 slopes with a height of 40-120 m based on the measured loess slopes in Jingbian-Ansai subregion of northern Shaanxi, China. The model is established using the finite element method, and the comprehensive shear strength parameters of different slope heights of the high slope in the study area are obtained by inversion using the Morgenstern-Price method. The results show that when the height of the slope increases, the cohesion c in the soil increases, and the internal friction angle φ decreases. According to the calculation results, a comprehensive inversion curve of strength parameters under the slope height of 40 to 120 m is drawn, which can directly evaluate the stability of the loess high slope, which improves the work efficiency and also provides reliable data support in the high side Slope geometry design.

Abstract
In the traditional pavement design, rainwater is mainly discharged by surface runoff, and in the structural design, the key point is the pavement waterproof. Therefore, the traditional sidewalk design is inconsistent with the requirements of sponge city. The research basis of this paper comes from a field engineering, the structural parameters of prefabricated sidewalk and the corresponding design methods are studied and summarized. The structural function of sidewalk is realized by superposition and combination of each structural layer. For the realization of prefabricated sponge sidewalk technology, the function of each structural layer must be fully considered, and the function of each structural layer should be designed and combined according to the design purpose. The results show that, by discussing the function of each layer of prefabricated sidewalk, the structural layer of prefabricated sidewalk is preliminarily determined(see Figure 2 in main text); according to the strength requirements and water permeability requirements of the structure, the thickness range of the structural layer is 13.11cm-21.3cm; finally, the relationship between plate thickness and critical position load, temperature fatigue stress, and finally determines the thickness of precast cement concrete slab is 15cm.

Published: November 2020

Abstract
This paper is aiming at control standard of frost heave deformation and freeze-thaw strength of cohesive soil of expressway widening subgrade in seasonal frozen region. Research was proposed to study the deformation law of high water content clay subgrade in freeze-thaw condition through laboratory test, field monitoring and theoretical analysis. According to the results, frost heave deformation control standard of cohesive soil subgrade has been proposed. Considering the overload load, the subgrade’s differential deformation rate should be less than 3.07‰ and the differential deformation rate must be less than 2.27‰. Considering the allowable bending tensile stress and the pavement structure service life, the differential deformation rate of the top surface of the subgrade under the effect of frost heaving of the high water content cohesive soil subgrade in the seasonal frost zone should be controlled within 2‰. After that, control standard for freeze-thaw strength of cohesive soil subgrade is put forward that, the subgrade-soil strength ratio of the high water content cohesive soil subgrade in the seasonal frost zone should be controlled within 0.75 under the standard load and within 1 under the overload load considering the allowable flexural stress and service life of the pavement structure.

Abstract
In prefabricated concrete structure, the shear performance of interfaces between prefabricated parts and cast-in-place parts needs improvement. Steel fiber self-compacting concrete is a desirable kind of concrete to solve this problem. This paper introduced Z-shape specimens with interfaces between new steel fiber self-compacting concrete part and old ordinary concrete part as direct shear experiment objects. Factors including steel fibers volume ratio and inserting rebars were also studied. The results show that the shear strengths of interfaces increase with the increases of steel fibers volume ratio, and inserting rebars can improve shear strengths and change failure form from brittle failure to ductile failure.

Abstract
Faba bean (Vicia faba) is an essential food and fodder legume crop worldwide due to its high content of proteins and fibres. Molecular markers tools represent an invaluable tool for faba bean breeders towards rapid crop improvement. Although there have historically been few V. faba genome resources available, several transcriptomes and mitochondrial genome sequence data have been released. These data in addition to previously developed genetic linkage maps represent a great resource for developing functional markers and maps that can accelerate the faba bean breeding programmes. Here, we present the Vicia faba Omics database (VfODB) as a comprehensive database integrating germplasm information, expressed sequence tags (ESTs), expressed sequence tags-simple sequence repeats (EST-SSRs), and mitochondrial-simple sequence repeats (mtSSRs), microRNA-target markers and genetic maps in faba bean. In addition, KEGG pathway-based markers and functional maps are integrated as a novel class of annotation-based markers/maps. Collectively, we developed 31 536 EST markers, 9071 EST-SSR markers and 3023 microRNA-target markers based on V. faba RefTrans V2 mining. By mapping 7940 EST and 2282 EST-SSR markers against the KEGG pathways database we successfully developed 107 functional maps. Also, 40 mtSSR markers were developed based on mitochondrial genome mining. On the data curation level, we retrieved 3461 markers representing 12 types of markers (CAPS, EST, EST-SSR, Gene marker, INDEL, Isozyme, ISSR, RAPD, SCAR, RGA, SNP and SSR), which mapped across 18 V. faba genetic linkage maps. VfODB provides two user-friendly tools to identify, classify SSR motifs and in silico amplify their targets. VfODB can serve as a powerful database and helpful platform for faba bean research community as well as breeders interested in Genomics-Assisted Breeding.
