ABSTRACT This study aims to develop an empirical equation to predict the California Bearing Ratio (CBR) based on the results of the TVA Penetrometer (Hand Cone Penetrometer) test on soft soils, particularly in coastal areas. Soil samples were prepared by mixing bentonite clay, kaolin, and sand, then compacted and tested in the laboratory to obtain CBR values and QcTVA readings. Stepwise re…

ABSTRACT Concentrically Braced Frame (CBF) is one of the commonly used seismic-resisting systems because it can effectively resist lateral forces. However, this system has a weakness, which is the risk of buckling under compressive forces that can reduce the structural capacity. Buckling Restrained Braced Frame (BRBF) is a development of CBF with restrainers that prevent buckling. This fin…

ABSTRACT The rise in traffic density in urban regions presents a threat of microplastic emission into the atmosphere. Road dust now contains microplastics, which are plastic particles that range in size from 0.001 to 5 mm. Due to their little weight and ease of airborne suspension, these particles have the potential to lower air quality and endanger human health. This study is to examine t…
