Published: March 2021

Abstract
Banyuwangi is a city with natural beauty and cultural uniqueness. One its cultures is Osing. Because it has many art performances, Banyuwangi does not yet have a special place to accommodate all art activities. Tourism in coastal areas has a high potential because it offers the beauty of natuew in every corner as its main atrraction. Banyuwangi Opera House is a combination of Banyuwangi Gandrung dance, patrol music, and Umbul-Umbul Blambangan song. Descriptive method was employed in this study using the results of comparative studies on art performance buildings that have cultural history. This design was made as an icon to describe the characteristics of Banyuwangi. The shape is an analogy from the typology of Osing Architecture consisting of tikel, baresan, and cerocogan by modifying the planes. Osing spatial planning includes bale, jrumah, and pawon with a space arrangement from front to back combine with colors identical to the distinctive Gandrung Sewu dance attire, namely red, yellow, and black. From the results of this study, it is expected that young generations can protect and preserve the wisdom of local culture through works of art.

Abstract
Special requirements of the service environment put forward higher requirements for the comprehensive performances of porous sound-absorbing materials. In this study, the polyimide/nano-SiO2 composite foams were prepared based via the sol-gel and foaming methods. The effect of different addition of SiO2 nanoparticles on the pore structure, sound absorption properties as well as the thermal properties of polyimide/SiO2 nanocomposite foams are studied. Results indicate that: the addition of the nano-SiO2 particles not only could improve the thermal stability of the composites, but also increase the sound absorption performances. Particularly, the samples with 2% addition of SiO2 nanoparticles shows the optimal thermal and sound absorption performance. Therefore, adding the SiO2 nanoparticles into the polyimide foams is an efficient way to improve its thermal and sound absorption performance, which would give insights into designing sound-absorbing materials with excellent comprehensive performance to curb the noise pollution.

Abstract
The hot compression deformation of 5356 aluminum alloy was performed with the deformation temperature 300∼500°Cand the strain rate 0.01∼10s−1 by using Gleeb1e-3500 thermal mechanical simulator. The microstructure of the alloy was analyzed by ZEISS metallographic microscope. The results show that the flow stress of 5356 aluminum alloy decreases with the increase of deformation temperature and increases with the increase of strain rate. 5356 aluminum alloy is mainly dynamic recovery under low strain rate conditions, such as 0.01 S−1, 0.1 S−1. The alloy is discontinuous dynamic recrystallization under high strain rate conditions, such as 1 S−1, 10 S−1. The hot processing map of 5356 aluminum alloy was established with the strain of 0.2∼0.5, can provide an effective data reference for the development of high-end 5356 aluminum alloy wire continuous rolling process.

Authors: Ran Longhua , You Lihui , Liu Wei , Wang Zhongqiang , Zhong Tieyi 
Published: March 2021

Abstract
In this paper, the present research status on the shear capacity of piers at home and abroad was reviewed, and the principles and methods of the nine formulas for calculating the shear capacity presented by domestic and foreign codes and scholars were introduced in detail. The nine formulas were compared with the test data from Chenglan railway bridge piers to discuss the existing problems. The results show that the calculation formulas proposed by some scholars are more complicated and more factors are taken into account, while the calculation formulas proposed by the codes are simpler and more conservative. The existing formulas for calculating the shear capacity of bridge piers are mostly acquired by fitting of the experimental data and it is too simple to consider reduction effect of the stress distribution and shear capacity of section concrete with the increase of displacement ductility, so it is difficult to evaluate the applicability. Therefore, further research on the calculation formula of shear strength for bridge piers is needed.

Abstract
According to the structural characteristics of aluminum conductor steel reinforced (ACSR), an experimental system is developed for the contact friction between steel and aluminum strands. The test parameters such as contact force and cross angle between strands are determined by the ACSR structure of JL1/G3A-1250/70-76/7. The curves of frictional force are obtained from the contact friction tests between steel core and aluminum strand, aluminum strand and aluminum strand under different conditions. The friction coefficient of strands under different contact conditions is obtained by statistical analysis, which provides support for further research on contact deformation analysis of strands in ACSR.

Published: March 2021

Abstract
On the basis of finding out the existing conditions of groundwater in the source area of Kang Ping power plant, GMS is used to construct the 3D perspective of aquifer structure and the numerical simulation model of groundwater flow system. According to the water demand of the water source area, two mining schemes are proposed. Based on GMS software, the groundwater flow field evolution of the two mining schemes in the study area from 2019 to 2022 is simulated by using the model. The results show that the overall groundwater level in the study area presents a stable situation under the mining condition of scheme I 9600 m3 / d, and under the mining condition of scheme II 12000 m3/d, the groundwater depression funnel is expanding. It is suggested to adopt scheme I comprehensively, the water supply capacity can be guaranteed, and the mining volume can be appropriately expanded in case of large water demand, but it should not exceed 12000 m3 / d.
Experimental Study on Influence of Vegetation Roots on Hydraulic Characteristics of Slope under Rainfall
Authors: Meng Suyun , Zhao Guoqing , Yang Yuyou 
Published: March 2021

Abstract
The water uptake by roots can change the soil permeability of slope. However, the affect mechanism of roots on hydraulic characteristics of slope under rainfall is insufficient. A laboratory test of vegetated slope and bare slope under rainfall was conducted to investigate the variety and distribution of suction. The influence of root water uptake on soil suction and water content of slope was studied. The soil water characteristic curve of bare slope and vegetated slope was established to study the influence of root water uptake on the water-holding capacity of soil. The results show that the influence range of root water uptake on the soil suction can reach twice the root depth, and the suction in the downhill position is smaller than that in the upward position induced by the lateral flow of water. In addition, root water uptake makes the suction of vegetated slope higher than that of bare slope, which will improve the water-holding capacity of soil, and then enhance the shallow stability of slope.

Published: March 2021

Abstract
The bearing capacity of the pile foundation determines the safety and stability of the upper structure. However, during the thermal cycling of the energy pile, the stress of the pile will be changed due to temperature changes., which will affect the bearing capacity of the energy pile foundation. In order to analyze the mechanical properties of the energy pile under multi-field coupling, the finite element software COMSOL Multiphysics is used to establish the thermal-mechanical coupling analysis model of the energy pile. We apply thermal load on the pile body and vertical load on the top of the pile. The results show that: Under the multi-field coupling of temperature and mechanical load, the energy pile body expands when heated, and the displacement of the pile top decreases; this will cause uneven settlement between the energy pile foundation laying the heat exchange tube and other pile foundations, which will lead to the tilt and damage of the superstructure; the stress of the pile during the heating of the energy pile will increase.
