Abstract: In this study, a numerical model is developed for the analysis of the free vibration of an open-type periodic structure, namely, a periodic viaduct supported by pile foundations. The viaduct is supposed to be composed of ...

Abstract: This study investigated anchorage behavior of geopolymer-grouted rock bolts. Pull-out tests were conducted on rock bolts grouted by geopolymer mortar (GM), geopolymer paste (GP), and cement mortar (CM), respectively. The ...

Abstract: A procedure is presented to develop probabilistic constant-strength ductility demand spectra based on statistical analyses of the results of comprehensive dynamic time history simulations of bilinear single-degree-freedom ...

Abstract: This paper presents comparative thermal and mechanical performance of geopolymers derived from metakaolin (MK), fly ash (FA), and their combinations. Bending and compression tests, thermogravimetric analysis, scanning ...

Abstract: A new process using a sequencing batch reactor (SBR) and two smaller sludge hoppers is proposed for the simultaneous removal of phosphorus and nitrogen from wastewater. In the double sludge switching sequencing batch ...

Abstract: In this study, a two-stage fractional programming (TSFP) method is developed for supporting municipal solid waste (MSW) management under uncertainty. The model can not only balance two conflicting objectives through ...

Abstract: To study the regular properties of modified bio-asphalt, analytical and measuring methods, including softening point, penetration, and ductility tests, were employed to analyze the improvement of properties in different ...

Abstract: Using field and quantitative surveys, the authors evaluated public attitudes toward and opinions regarding plant landscaping low-impact development (LID) in the city of Hangzhou, China. The results showed that the public ...

Abstract: Heavy glulam timber framed structures are facing a growing inadequacy in resisting lateral actions from earthquakes and winds due to the increasing building heights. This paper presents the experimental and numerical ...
