“…The remaining materials that have considerable production and are landfilled are major plastic materials and often C&D materials Table 4. In either case, however, it is believed that the recent development in structural engineering area (e.g., [198][199][200] along with the use of novel technologies will make the most of the available materials for the production of sustainable, highperformance structures.…”

Due to constant growth of waste production, recent strategies in waste management such as circular economy promote the maximum life cycle use of materials. In construction industry where structures tend to last for decades, the use of such recycled materials can have numerous benefits including overall reduction in cost, in use of virgin materials, and in CO2 production as well as providing an opportunity for a tailored concrete with specific properties. Yet, because of the stereotypical and negative image of mechanical properties reduction, as a result of using waste materials, often their vast contribution in sustainability and durability properties are not taken into consideration. In this regard, we propose viewing waste materials as secondary raw materials that in certain regards, can provide a favorably tailored property. In this regard, the following review article first provides a short description of the most commonly used waste materials such as supplementary cementitious materials (fly ash, ground granulated blast furnace slag, silica fume, metakaolin, rice husk ash, municipal solid waste ash, steel slag, copper slag), ceramics from construction and demolition (glass powder, brick and tile ceramic and porcelain), and the vastly available plastic materials (polypropylene, polyethylene terephthalate, polyvinyl chloride, and rubber). Then, by reviewing a selected environmental impact (life cycle assessment), physicochemical, durability, and finally mechanical properties discuss the limitations, future projections of newer waste materials (e.g., agricultural waste) to be used and suggest potential future study in this area.

Effect of Competent Caliche Layers on Measuring the Capacity of Axially Loaded Drilled Shafts Using the Osterberg Test

2020

This study investigates the effect of the location of an O-cell hydraulic jack along the length of a drilled shaft in a full-scale Osterberg test performed in soils containing layers of caliche. The location of the hydraulic jack with respect to caliche layers influences the measurements obtained from the Osterberg test and the subsequent interpretation of drilled shaft capacity. In this study, drilled shaft capacities were derived utilizing data from 30 Osterberg full-scale field load tests in soils containing caliche layers. The hydraulic jack was placed at the midpoint of the drilled shaft length. Additionally, the Osterberg test data was used to calibrate a numerical model by Plaxis finite element software for drilled shaft analysis. Using the calibrated model, several scenarios of hydraulic jack location were simulated. The scenarios included hydraulic jack locations at several distances above and below a caliche layer. The results of the simulations indicate that in cases where the O-cell was installed far from the caliche layer, the Osterberg tests results showed lower pile resistance capacity compared to the top-down test. However, in cases where the O-cell was installed close to the caliche layers, the Osterberg tests results showed comparable pile resistance capacity compared to the top-down tests. This study recommends installing the hydraulic jack as close as possible to the caliche layers for more reliable interpretation of the Osterberg field tests which leads to a cost-effective design approach by reducing the required shaft length.

“…On the other hand, under a moderate earthquake, it is not economically justifiable to designing a structure which remains elastic [5][6][7]. So, in order to dissipate earthquake energy, the structure should experience inelastic behavior [8][9][10][11][12][13][14][15]. Extensive research has been performed to increase the ductility of concentric braces [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31].…”

This paper treats a different type of bracing by using circular bracing elements called OGrid-H. The goal of using circular shape is to obtain more ductility, high performance and appropriate stiffness and limit the buckling of braces, and at the same time in order to realize a solution that is interesting from the architectural point of view. In order to study the seismic behavior of OGrid-H members, a numerical finite element analysis of 9 OGrid-H models with different section members is established through ABAQUS finite element software subjected to cyclic loadings, which failure modes, load capacity, nonlinear displacement, ductility factor, vibration period, stiffness and energy absorption of models is obtained, and the comparison between outputs of models leads to obtaining the model with the best sections which have higher performance than the others. In order to investigate the OGrid-H connections, five changes are applied on connections, which the results showed that three changes had the greatest influence, which caused to increase load bearing as the amount of 22.88%.
