Numerical Investigation of Distribution Laws of Shear Force in Box Girder Webs by Xingwei Xue, Chao Zang, Junlong Zhou, Hai Zhang

“…The results show that supporting conditions and chambers have a significant impact on the shear-increased coefficient η, and end diaphragm must be set up in the 3D finite element model when calculating η. Nonlinear analysis shows that in the elastic phase, the shear-increased coefficient η basically does not change, but in the cracking stage, the coefficient η of each web changes with the degree of web cracking, and side-webs (S-Webs) reach the ultimate load first. …”

Investigation of Artery Wall Elasticity Effect on the Prediction of Atherosclerosis by Hemodynamic Factors by Rasool Kalbasi, Bahador Sharifzadeh, Mehdi Jahangiri

“…The results also revealed that for simple stenosis, the length of the diseases prone zone in the elastic artery is 21% longer than the rigid one which this figure for double stenosis is calculated to be about 40%. Comparing the results of the simple stenosis with double, one affirmed that the artery wall thickness growth for case of double stenosis is greater than that of the single one.…”

Study on Flood Evolution Law of Typical River Basins in Daqinghe Mountain Area under Changing Environment by WANG Siqi, ZHU Hongpeng, LU Fan, JIANG Ming, ZHOU Yuyan

“…Among the major river basins in China,Haihe River basin is greatly affected by environmental changes in terms of hydrological situations.Therefore,in-depth studies on the impact of environmental changes on flood evolution in the basin are of practical significance.Two typical sub-basins at the upper reaches of Zijingguan hydrological station and Fuping hydrological station are selected,and the two stations are located in the Daqinghe mountain area of the Haihe River basin.According to the flood process and precipitation data of the annual maximum flood peak of the two stations from 1960 to 2018,the changes in flood process,runoff coefficient,and runoff threshold are analyzed by mathematical statistics and other methods,and a time-varying parameter model GAMLSS is used to analyze the changes in flood frequency under inconsistency conditions.The results show that the flood peak discharge of the two sub-basins decreased significantly from 1960 to 2018,and the average value of flood peak discharge and runoff coefficient in different stages became small gradually.The average values of runoff threshold of the two sub-basins were 14 and 16 mm,respectively,from 2000 to 2018.The hydrological inconsistency caused by the change in underlying surfaces has a significant impact on the design flood value,and follow-up analysis and calculation of hydrology should pay attention to the impact of environmental changes on hydrological series.…”
