    Abstract: The number of waste tires is increasing in recent decades. Landfilling and incineration are not only consuming the land resources, but also severely endangered the ecological environment and human health. Therefore, how to recycle waste tires effectively becomes an urgent issue. Certain researches have established that crushing waste tire into powd... Show More

    Abstract: In this paper, we propose a method for the direct determination of the Young's modulus of soils from the Standard Penetration Test by performing back-calculations iteratively knowing the reference sinkage which is 30 cm. We modeled the Standard Penetration Test taking into account the experimental protocol in the field and the typical Impulsive loa... Show More

    Abstract: During the construction of building structures, the transfer platform is the main passage of materials entering or departing the floor, and it is an important facility for site operation. In recent years, a large number of construction accidents have occurred due to unsafe design and unreasonable site practices of the transfer platform, and serious... Show More

    Abstract: At present, there are few application cases of segmental prefabricated concrete T-section beams in bridge structures, and the research on mechanical properties is still insufficient. The division of segments makes the beam body have multiple joints, and the longitudinal reinforcement cannot be arranged continuously, which results in the discontinuo... Show More

    Abstract: Dam evaluation needs to be carried out, to look back at the deformation of the dam structure during decades of operation. In this study, the structure of Wadaslintang dam will be evaluated based on dynamic earthquake loading on the basis of the 2019 Indonesian earthquake hazard map. Dynamic evaluation of the dam requires dynamic earthquake accelera... Show More

    Abstract: In general, pH-sensitive colorants such as phenolphthalein are applied on freshly split surfaces of building structures to determine the state of carbonation. For years, it has been known that the aerosols of phenolphthalein are suspected of being carcinogenic. Hence, more work has currently being done on alternative indicators for the use in resea...
