| 1 | Resilience-based retrofitting of existing urban RC-frame buildings using seismic isolation显示文摘The improvement of the seismic resilience of existing reinforced-concrete(RC) frame buildings, which is essential for the seismic resilience of a city, has become a critical issue. Although seismic isolation is an effective method for improving the resilient performance of such buildings, target-oriented quantitative improvements of the resilient performance of these buildings have been reported rarely. To address this gap, the seismic resilience of two existing RC frame buildings located in a high seismic intensity region of China were assessed based on the Chinese Standard for Seismic Resilience Assessment of Buildings. The critical engineering demand parameters(EDPs) affecting the seismic resilience of such buildings were identified. Subsequently, the seismic resilience of buildings retrofitted with different isolation schemes(i.e., yield ratios) were evaluated and compared, with emphasis on the relationships among yield ratios, EDPs, and levels of seismic resilience. Accordingly, to achieve the highest level of seismic resilience with respect to the Chinese standard, a yield ratio of 3% was recommended and successfully applied to the target-oriented design for the seismic-resilience improvement of an existing RC frame building. The research outcome can provide an important reference for the resilience-based retrofitting of existing RC frame buildings using seismic isolation in urban cities. | Yang Cantian Xie Linlin Li Aiqun Zeng Demin Jia Junbo Chen Xi Chen Min | 2020 | Earthquake Engineering and Engineering Vibration2020，19，4： | 7 |
| 2 | Bisphenol-A epoxy resin reinforced and toughened by hyperbranched epoxy resin显示文摘The study on toughening and reinforcing of bisphenol-A epoxy resin is one of important developmental direction in the field.This paper reports a one-pot synthesis of aromatic polyester hyperbranched epoxy resin HTDE-2,an effect of HTDE-2 content on the mechanical and thermal performance of the bisphenol-A(E51)/HTDE-2 hybrid resin in detail.Fourier transform infrared(FT-IR)spectrometer,scanning electronic microscopy(SEM),differential scanning calo ri metry(DSC),thermogravimetric analysis(TGA),dynamic mechanical thermal analysis(DMA)and molecular simula tion technology are used to study the structure of HTDE-2,performance and toughening and reinforcing mech-anism of the HTDE-2/E51 hybrid resin.It has been shown that the content of HTDE-2 has an important effect on the performance of the hybrid resin,and the performance of the HTDE-2/E51 blends has maximum with the increase in HTDE-2 content.The impact strength and fracture toughness of the hybrid resin with 9 wt-%HTDE-2 are almost 3.088 and 1.749 times of E51 performance respectively,furthermore,the tensile and flexural strength can also be enhanced about 20.7% and 14.2%,respectively.The glass transition tem-perature and thermal degradation temperature,however,are found to decrease to some extent. | ZHANG Daohong JIA Demin HUANG Xianbo | 2007 | Frontiers of Chemical Science and Engineering2007，1，4： | 3 |

| 4 | Construction and characterization of a bacterial artificial chromosome library of rice 5460F显示文摘Thermo-sensitive genie male sterile (TGMS) rice has a number of desirable characteristics for hybrid rice production. Many studies have demonstrated that the sterility of TGMS rice is controlled by a single recessive gene. It has been mapped for the first time on chromosome 8 and named tms1. Several AFLP markers which tightly linked to the tms1 gene have been identified recently. In order to develop a detailed physical map of the tms1 gene-encompassing region and finally clone the tms1 gene, a bacterial artificial chromosome (BAC) | Jianmin Fu Xueping Qu Chuanyou Li Jianhang Jia Demin Jin Qian Wang Rencui Yang Bin Wang | 1999 | Chinese Science Bulletin1999，44，17： | 2 |
