Speech Title: Analytical approximations for the frequency response, localization factor and attenuation coefficient of one-dimensional periodic foundations（一维周期基础频率响应、局部化因子及衰减系数的解析近似解）
Abstract: This research studies the frequency related properties of one-dimensional periodic foundations and further proposes analytical approximations for the frequency response, localization factor and attenuation coefficient of these structures. The proposed analytical approximations are validated numerically. In addition, a matrix of frequency responses are defined and used in the investigation of the corresponding superstructure-foundation coupling effect.

Speech Title: Experimental Investigation of Seismic Uncertainty Propagation through Shake Table Tests （基于振动台试验的地震不确定性影响研究）
Abstract: The propagation of uncertainty in seismic response analysis is the mechanism through which ground motion (GM) uncertainty and structural parameter (SP) uncertainty contribute to response variability, and is critical for accurately quantifying seismic risk in performance-based earthquake engineering (PBEE). Response uncertainty in existing PBEE analyses is estimated either through statistical variance combination approaches or through computationally intensive time history simulations. In general, experimental exploration of the uncertainty propagation is cost prohibitive and impractical. In this paper, a series of shake table tests are conducted to generate statistical seismic response data of 12 nominally identical simple specimens subjected to a suite of 7 earthquakes at different seismic intensity levels. The test data are analyzed in order to decouple the contributions of GM uncertainty and structural parameter uncertainty on response uncertainty with different intensity levels and verifying several basic characteristics about uncertainty propagation. In addition, the accuracy of the square root sum of squares (SRSS), which is a simplified method used to combine different uncertainty sources to calculate the total response uncertainty, is evaluated through comparison with test data.

Experimental study on mechanical behavior of basalt fiber reinforced cemented soil subjected to complex environment in season frozen zone
In the seasonal frozen area, the freezing-thawing cycles and the erosion of the external environment are the main factors affecting the strength of cemented soil. It is an important topic to explore the development law of mechanical properties of cemented soil subjected to the complex environment in the seasonal frozen area and how to improve its mechanical properties. In this paper, a series of unconfined compressive strength tests, freezing-thawing cycle tests, salt freezing tests were carried out to analysis the influence of fiber content and fiber length on the mechanical properties of cemented soil. And then the influence of curing temperature, curing time, number of freezing-thawing cycles, salt freezing environment on the mechanical properties of basalt fiber reinforced cemented soil was discussed. The results show that the strength of basalt fiber reinforced cemented soil presents a generally convex curve with the increasing of fiber length, and the curve finally tends to the strength of cemented soil without fiber under the same fiber contents. It shows that the fiber distribution uniformity and fiber distribution density have great influence on the strength. The strength of basalt fiber reinforced cemented soil presents a wavy curve with the increasing of fiber content, the second wave peak value is less than the first wave peak value and the curve finally tends to a fixed value under the same fiber length. As the number of freeze-thaw cycles increased，the strength of the fiber-reinforced cemented soil tended to decrease． The strength of cemented soil without fiber decreased the most． The relationship between the strength and the number of freeze-thaw cycles was linear. Under the same number of freezing-thawing cycles, the damage degree of basalt fiber reinforced cemented soil is sulfate-freezing > mixed salt freezing > chloride salt freezing > water freezing. The research shows that the addition of basalt fiber can not only improve the mechanical properties of cemented soil, but also improve the resistance to the influence of complex environment such as freezing-thawing and salt freezing. The study in this paper can provide some reference for the application of basalt fiber reinforced cemented soil in the complex environment of seasonal frozen area.

Retrofitting diesel-powered construction equipment for clean construction in Hong Kong
Construction equipment is the power house in construction of buildings and infrastructure projects as many activities, such as land preparation and excavation, foundation works, installation works, concrete works, mainly rely on heavy equipment for implementation. However most construction equipment items are diesel powered and emit toxic pollutants of particulate matters (PM), Nitrogen oxides (NOx), unburned hydrocarbons (HC), carbon monoxide (CO), which are important sources of air pollutions detrimental to the health of construction workers and the general public near the site. This study briefly summarizes the available retrofitting and emission reduction technologies of diesel engines in terms of their affordability, effectiveness, technology maturity, services and support through literature review and analysis, and then applies selected retrofitting technologies to the current in-service construction equipment and evaluate their cost benefits through life cycle analysis on selected construction equipment from a large general contractor in Hong Kong. Recommendations are made on how the government can provide supports and inventive to the contractors so that the main contractors can take progressive actions to retrofit and upgrade of their equipment fleet to achieve clean construction in project development, while in the same time, operate with a viable financial plan to reduce its impact on project budget.
