Authors: Tang Yu Chao , Huang Xian Huai , Tang Li Hua , Li Xin , Xue Li Ping , Yao Yuan Jun , Wang Li Juan
Published: August 2011

Arsenite(III) and arsenate(V) removal from low-arsenic concentration drinking water by amorphous and anatase TiO2 adsorbents were studied in this paper. X-ray diffraction (XRD) and BET surface area analysis were used to characterize the physical and chemical properties of the adsorbents. Pore size calculated from adsorption average pore width (4V/A by BET) is 3.92 nm of amorphous TiO2 and 11.0 nm of anatase TiO2. The BET surface specific area of amorphous TiO2 was found to be 205 m2/g and anatase TiO2 was 115.6 m2/g, respectively. Amorphous TiO2 shows more efficiency than anatase TiO2 for As(III) and As(V) removal. About 80% of As(V) and 60% of As (III) can be removed within 2h reaction when dosage of amorphous TiO2 was only 0.1g/L. High temperature can facilitate the adsorption of As(V) but exhibit no obviously influence on As(III). Adsorption kinetics data were found to be best described by the modified pseudo-second-order kinetics model which can be described by Equation 1/(Qe-Qt)-1/Qe=k∙tn for arsenite(III) and arsenate(V) removal.

Authors: Lan Zhang Li , Zhang Hong , Zhou Yi , Xiang Li Na , Wang Jing
Published: August 2011

This paper presents an inclinometer-based deflection curve reproduction system which can reconstruct the deflected shapes of bridges directly. Because the conventional deflection-measuring methods are performed by collecting the deflection data at just a few discrete points along the bridges, the bridges’ deflected curves are not smooth enough. The operation of the proposed system is performed by utilizing the displacement transducer to determine the measuring intervals, using inclinometer to collect the angles of the measured points, calculating the deflection values, further applying Gradient Mean Prediction Filtering (GMPF) algorithm to filter the deflection data, and finally reproducing the deflection curves of bridges. The precision, feasibility, reliability, and effectiveness are verified by laboratory tests and field applications.

Application of Mathematical Morphological Filter in Vibration Signal Processing
Authors: Hu Ai Jun , Sun Jing Jing , Ma Wan Li
Published: August 2011

The morphological filter as a nonlinear filtering method has been widely used for image (or signal) processing. Unlike the traditional digital filters, mathematical morphological operations are shape-based computing. Feature extraction of signals is entirely in the time domain without the transforming of the signal from the time domain to frequency domain. The vibration signal contaminated with noise is processed using morphological filter and Butterworth filter respectively. To compare the outputs of the two filters, we find that morphological filter shows better performance. It is effective in suppressing noise while maintaining the original signal both in the time and frequency domain. In addition, an outstanding advantage of morphological filter is its ability to keep the phase of the original signal. Its computing speed is faster. In the end, its low-pass characteristic is verified by processing vibration signal.

Authors: Li Xue Yan , Law S. S , Wang Li Xin
Published: August 2011

A new matrix on the covariance of covariance is formed from the auto/cross-correlation function of acceleration responses of a structure under white noise ambient excitation. The components of the covariance matrix are proved to be function of the modal parameters (modal frequency, mode shape and modal damping) of the structure. The number of vibration modes associated with components of the matrix is only limited by the sampling frequency. Compared to the general methods for extracting modal parameters, the formulated covariance matrix contains more information on the vibration modes of the structure. An in-service suspension bridge is analyzed. Only the output acceleration responses are used to compute the covariance of covariance (CoC) matrix and the Pattern Assurance Criterion (PAC) values. From the CoCs variation and the changing trend of the PAC curve, the healthy condition of the bridge is assessed. The method is independent of analytical model and huge amount of data can be analyzed. It is especially suitable for long-term on-line health monitoring of a structure.

Seismic frequency-magnitude relationship has been investigated in China, based on the earthquake data in the range ofM3.0 toM7.0 during the years 1986-2008, to study the potential of variations ofb-values with the depth. According to the results, there is a systematic decrease inbvalue with increasing depth of earthquakes. At the shallow depth conditions, with more heterogeneous material properties and lower lithosphere stress prevail, rupture initiation is more likely to stop before accumulating into large earthquakes, producing relatively smaller earthquakes and consequently higherb-values. On the contrary, the larger earthquakes are more likely to happen at a greater depth.
Modified Acoustic Emission Source Localization Method to Determine Crack Locations for Masonry Arch Bridge
Authors: Xu Jie , Lacidogna G.
Published: August 2011

In this paper, the applicability of the source localisation method in Acoustic Emission (AE) technique to determine the crack locations in masonry is investigated. A series of pencil-break tests are performed on a two-span masonry arch bridge. Because of the layered structures, the assumption of homogeneous material and uniform velocity field in the classical method for concrete is not suitable in the masonry structures. The velocity is not uniform but shows a downdraught with the increasing distance due to the layered material structure. Based on this property, a modified AE source localization method is proposed. The modified factor in the model greatly reduces the effect of the inhomogeneity. The testing results from the pencil breaks and the central pier settlement tests highlight the effective of the modified method.

In such a relatively enclosed space with lack of natural light and poor air circulation, the unfavorable influence of decorative materials on human beings’ physiology and psychology grows more remarkable. This paper intends to make a preliminary study on the ways of applying the decorative materials to satisfy more reasonably the people physical and mental demands, thus exploring a new design concept on the application of material.
CAIs for Measuring Benefits of Rural Infrastructure Investment in China
Authors: Jiang Shi Jie , Shen Li Yin , Peng Yi , Zhou Li
Published: August 2011

This paper identifies a set of critical assessment indicators (CAIs) that can evaluate the multifaceted benefits of rural infrastructure investment in China. Research data were collected from a questionnaire survey to three groups of experts including government officers, professionals and business practitioners who are working in China’s housing and urban-rural development sector. The Fuzzy Set theory is used for establishing the CAIs, which appreciates the fuzziness of data from the questionnaire survey and thus increases the adequacy in the selection of the CAIs. The CAIs can help the local governments to make better decisions in investing in rural infrastructure in China. These critical indicators can also be generalized to provide valuable references for the investigation of rural infrastructure investment in other developing countries.

Authors: Ning Xin , Wang Li Guo
Published: August 2011

Effective construction site layout planning (CSLP) shall improve construction operations efficiently and enhance work environment safety. The majority researches works on CSLP focused on developing different algorithms and program to generate site layout alternatives using quantitative and qualitative factors involved in the interaction flows. However, some qualitative factors, such as security and noise control are not taken into consideration. This study proposed intuitionistic fuzzy TOPSIS method to evaluate and select the best site layout from site layout alternatives in terms of the project-specific attributes, which are neglected and hard to quantify in generating site layout alternatives. The results show that the proposed method improves the quality of decision making in evaluation and selection of the best construction site layout.
Using Cable Restrainers to Mitigate the Seismic Pounding between Adjacent Structure Members
Authors: Zhou Guo Liang , Meng Qing Li
Published: August 2011

Damages of adjacent bridge girders due to pounding observed in Wenchuan earthquake are introduced in this paper. Based on Niulanjiang Bridge built in Yunnan province, nonlinear time history analyses are performed considering non-uniform seismic ground motion excitations, which are obtained by site seismic response analysis of the local canyon topography. And the effectiveness of cable restrainer device against unseating is studied through numerical simulations. The results show that pounding between adjacent segments of the bridge may obviously amplify the relative deformation of expansion joints, resulting in a higher probability of unseating. Cable restrainers can not only reduce the relative deformation of the expansion joints, but also mitigate the response of isolators. It also indicates that the cable restrainers can observably reduce the response of piers.
