Development Strategy of National Quality Infrastructure in China

Gong Kenan, Yu Lianchao, Xu Xuelin

Strategic Study of CAE 2021, Volume 23, Issue 3, Pages 46-52 doi: 10.15302/J-SSCAE-2021.03.015

Abstract:

National quality infrastructure (NQI) is the technical foundation of a country’s high-quality development and an important component of the national innovation system. Improving the technical capacity and management level of the NQI is a key means to promote China’s strength in science and technology and product quality. Conducting strategic research on NQI is critical for transforming China from a country of quantity to a country of quality. This study analyzes the status quo and existing problems in the development of quality infrastructure in China and abroad and proposes the overall idea, objectives, and future direction of the NQI development strategy for China. Furthermore, we propose several policies to provide support and reference for the scientific development of China’s NQI, including clarifying the strategic positioning of NQI, optimizing the construction of NQI, consolidating NQI technical foundations and systemic services, strengthening diversified resource investment, and participating in the international exchanges of NQI.

Shaking table testing of hard layered soil-pile-structure interaction system

LI Peizhen, REN Hongmei, LU Xilin, SONG Heping, CHEN Yueqing

Frontiers of Structural and Civil Engineering 2007, Volume 1, Issue 3, Pages 346-352 doi: 10.1007/s11709-007-0046-7

Abstract: Shaking table tests on a dynamic interaction system of hard layered soil, pile foundation and frame structure were carried out. The earthquake damage of the superstructure and foundation was reproduced. Based on these tests, several key issues about the seismic response of the dynamic soil-structure interaction (SSI) system were studied. The natural frequency of the system was less than that of the structure on rigid foundation if the SSI is not taken into account, while its damping ratio was larger than that of the structure. The mode shape of the system was different from that of the structure on the fixed base in that there were rocking and swinging at the foundation. Magnification or reduction of vibration transferred by soil was related to soil characteristic, excitation magnitude, and so on. Generally, sand magnifies vibration, while viscous powder soil dampens vibration. The components of the acceleration response at the top of the superstructure were based on the relative magnitude of the rocking stiffness, the swing stiffness of the foundation and the stiffness of the super-structure. The multi-direction excitations have little effect on the key issues of the horizontal SSI.

Keywords： super-structure Generally Magnification frequency different

Experimental monitoring of the strengthening construction of a segmental box girder bridge and field testing

Ali Fadhil NASER, Zonglin WANG

Frontiers of Structural and Civil Engineering 2012, Volume 6, Issue 3, Pages 308-320 doi: 10.1007/s11709-012-0140-3

Abstract: Prestressed concrete segmental box girder bridges are composed of short concrete segments that are either precast or cast in situ and then joined together by longitudinally post-tensioning internal, external, or mixed tendons. The objectives of this study are to monitor the construction process of the external prestressing tendons to strengthen the bridge structure and perform a field load test to measure the strain and the deflection of the anchorage devices of the external prestressing tendons to determine the state of these devices after tension forces are applied. The monitoring process of the external prestressing tendons construction includes inspecting the cracks in the diaphragm anchorage and the deviation block devices before the tension forces are applied to the external tendons; measuring the deformation of the steel deviation cross beam during the tension process; measuring the deformation of the box girder after different levels of tension forces are applied; measuring the elongation of the external tendons in each level of the tension; and measuring the natural frequency of the external tendons after the tension process is complete. The results of the monitoring process show that the measured values of the deformation, the elongation, and the natural frequency meet the requirements. Therefore, there is no damage during the construction and the tensioning of the external prestressing tendons. A field load test is performed to the anchorage beam, the steel deviation block devices, and the steel deviation cross beam. The field load test results of the anchorage devices show that the values of the strains, the stresses, and the deflection are less than the respective allowable limit values in the requirements. Therefore, the anchorage devices have sufficient strength, and the working state is good after the tension forces are applied to the external prestressing tendons.
