In civil engineering, revolving structures (RS) are a unique structural form applied in innovative architecture design. Such structures are able to revolve around themselves or along a certain track. However, few studies are dedicated to safety design or health monitoring of RS. In this paper, a wireless dynamic sensing system is developed for RS, and field tests toward a large revolving auditorium are conducted accordingly. At first, a wheel-rail problem is proposed: The internal force redistributes in RS, which is due to wheel-rail irregularity. Then the development of the sensing system for RS is presented. It includes system architecture, network organization, vibrating wire sensor (VWS) nodes and online remote control. To keep the sensor network identifiable during revolving, the addresses of sensor nodes are reassigned dynamically when RS position changes. At last, the system is mounted on a huge outdoor revolving auditorium. Considering the influence of the proposed problem, the RS of the auditorium has been designed conservatively. Two field tests are conducted via the sensing system. In the first test, 2000 people are invited to act as the live load. During the revolving process, data is collected from RS in three different load cases. The other test is the online monitoring for the auditorium during the official performances. In the end, the field-testing result verifies the existence of the wheel-rail problem. The result also indicates the dynamic sensing system is applicable and durable even while RS is rotating.

The whole plant of Euphorbia helioscopia is an important traditional Chinese medicine. Fom its BuOH soluble extract,one new lactam (1), three new terpenoids (2-4) including a new naturally occurring compound, and three known compounds were isolated. Their structures were identified by spectroscopic evidences. In particular, the absolute configurations of side chain of compounds 1 and 2 were determined using computational methods.

Improved Performances of AlN/Polyimide Hybrid Film and its Application in Redistribution Layer
Zhe Liu,Guifu Ding,Jiangbo Luo,Wen Lu,Xiaolin Zhao,Ping Cheng,Yanlei Wang 대한금속·재료학회 2016 ELECTRONIC MATERIALS LETTERS Vol.12 No.5
The AlN/polyimide (PI) hybrid film was studied as thedielectric layer in the redistribution layer (RDL) in this work. The incorporation of the AlN into the PI matrix was achievedby mechanical ball-milling process. The spin-coating processwas used to fabricate the AlN/PI hybrid film, which iscompatible with micro-electro-mechanical system (MEMS)technology for fabricating RDL. The AlN/PI hybrid film wascharacterized by Fourier transform infrared (FTIR) spectrumand thermogravimetric analysis (TGA). The effect of the AlNcontent on the thermal stability, thermal expansion coefficient,hardness and water adsorption of the AlN/PI hybrid film wasstudied. The results indicated that the addition of AlN nanoparticlesimproved the thermal stability and hardness, butdecreased the thermal expansion coefficient and waterabsorption of the pure PI film. As an example of its typicalapplication, the AlN/PI hybrid film with 8 wt.% AlN waspatterned using micromachining technology and used as thedielectric layer in RDL successfully.

Elastic Foundation Beam Solution of Tensile Flexible Retaining Wall
Xu Jianqiang,Xu Jiangbo,Yang Xiaohua,Yan Zhaobai,Li Haiping,Wang Huoming,Tan Ling,Fei Dongyang,Li Jianguo,Luo Yongzhen 한국강구조학회 2022 International Journal of Steel Structures Vol.22 No.2
The application of fl exible retaining walls in foundation pit engineering is gradually increasing. At present, many practical engineering problems need to be solved. This article takes a corrugated steel retaining wall with tensile reinforcement, for example, assuming that it is an elastic foundation beam model. A typical vertical thin layer unit is taken on the retaining wall for analysis. It uses the waveform integration method to calculate the moment of inertia, deriving the diff erential equation of fl exural deformation of corrugated steel retaining wall and establishing the theoretical formula for deformation of corrugated steel retaining wall under fi lling pressure behind the wall. Finally, a FLAC3D model was established to simulate the deformation of corrugated steel retaining walls in practical engineering, and the fi nal numerical simulation results were consistent with the theoretical formula. Thus, providing a theoretical basis for the deformation of such fl exible retaining structures.
