In recent decades, the dual systems of steel moment-resisting frames and RC shear walls have found extensive application as lateral load-resisting systems for high-rise structures in seismically active areas. This paper investigated the effectiveness of tuned mass damper (TMD), viscous damper, friction damper, and the lead-core rubber bearing in controlling the damage and seismic response of hi...

The strength comparison of fibre reinforced peat and clayey-silt for the compacted sub-grade by using reinforcement technique from scrap tire is presented. tires are extracted shredded into a standard size, i.e., rubber-chip, rubber-crumb, rubber-powder fibre-polyester consistency homogeneity design mix. In this study, two types fibres used, which polyester rubber crumb. at various designated p...

Abstract—The solution of the nonlinear dynamic equilibrium equations of base-isolated structures adopting a conventional monolithic solution approach, i.e. an implicit single-step time integration method employed with an iteration procedure, and the use of existing nonlinear analytical models, such as differential equation models, to simulate the dynamic behavior of seismic isolators can requir...

The purpose of base isolation is to absorb earthquake energy, prolong the life structure, and enable structure be similar a rigid body. However, since resonance can occur due closeness period structures long large velocity pulses near field earthquakes, stability these buildings greatly reduces, with displacement above level, sometimes, tendency overturning created in isolators leading their de...

This paper focuses on the application of triangulation and rubber-sheeting techniques to the problem of merging two digitized map files. The Census Bureau is currently developing a map merging procedure called conflation. Reproducibility, quality control, and a desire for mathematical consistency in conflation lead to a need for well-defined procedures. The Delaunay triangulation is well-define...

INTRODUCTION Most astronauts experiencing prolonged microgravity undergo accelerated bone loss at a whole-body rate of 0.5-1% per month, with some load-bearing bones losing mass at normalized rates up to about 2.6% per month. The accompanying release of lead (Pb) stored in bones would increase the concentration of Pb in the blood (PbB), thereby complicating efforts to set acceptable Pb concentr...
