The erythrocyte membrane skeleton is the best understood cytoskeleton. Because its protein components have homologs in virtually all other cells, the membrane serves as a fundamental model of biologic membranes. Modern textbooks portray the membrane as a 2-dimensional spectrin-based membrane skeleton attached to a lipid bilayer through 2 linkages: band 3–ankyrin– spectrin and glycophorin C–prot...

In this work, the effect of rock bolt angle on the shear behavior of Rock Bridges is investigated using the particle flow code in two dimensions (PFC2D) for three different Rock Bridge lengths. Firstly, the calibration of PF2D is performed to reproduce the gypsum sample. Then the numerical models with the dimensions of 100 mm * 100 mm are prepared. The Rock Bridge is created in the middle of th...

scour around bridge piers is one of the most important fields of hydraulic research. local scour around bridge piers and abutment is one of the main reasons of bridge failures. in the field of scour at the bridges, researches are more focus on scour of piers in compare with abutment. while the available information on the bridge failures required cost, the major problems are related to abutment...

The increase in population every year makes more and owners of motorized vehicles cars resulting full access to the highway, not only highway that experiences density while bridge is one factors due number pass at a certain time will be congested experience enough vibrations because load carried by different, greater held bridge, vibrates, therefore writer make an instrument using geophone sens...

Abstract This paper deals with experimental and numerical dynamic analyses of two timber footbridges. Both bridges have a span 35 m consist deck supported by arches. The main purpose is to investigate if the properties are season dependent. To this end, tests performed during cold day in winter warm spring Sweden. first bending transverse mode frequencies increase 22% 44%, respectively, due tem...

Abstract Many researchers have carried out experimental and numerical investigations to examine building structures’ response explosive loads. Studies of bridges subjected blast loads are limited. Hence, in this study, we present a case study on cable-stayed bridge, namely, Charles River Cable-Stayed Bridge-Boston, assess its robustness resistance against the progressive collapse resulting from...
