The main factors affecting the load-bearing capacity of new and damaged stone structures are given. One most common types damage to buildings is their cracking. According statistics, frequent reasons for formation cracks in are: uneven settlement foundations, load on structures, temperature deformations, moisture deformations. walls depends compressive strength bricks mortar, but it difficult m...

As a new type of deep-sea anchoring foundation, thetorpedo anchor has the characteristics simple installation, low cost, and high bearing capacity. Compared with torpedo without an wing, end-bearing forms pile end resistance using plate, thus further improving its uplift By conducting pullout model test anchors, we have compared analyzed effects angle bearing-plate radius on T, EN3, EN4, EC typ...

In this study, the co-operation of steel and concrete in composite columns is considered. Using numerical modeling to study the behavior of these sections, a new type of sections, namely Concrete Filled Double-Skin steel Tubular (CFDST) columns, is introduced. The parameters and techniques that influence the numerical simulation that bring this modeling closer to...

In tribology, the Rayleigh step bearing has maximum load capacity of any feasible geometry. Traditional tribology resources have demonstrated that an ideal geometry which maximizes capacity. Both in nature and technology, rough textured surfaces are essential for lubrication. While surface roughness enhances performance bearings as efficiency measure, it still a significant impact on load-carry...

Pretensioned prestressed high strength concrete (PHC) pipe piles are widely used in various engineering foundations, which have the advantages of single pile bearing capacity, strong adaptability to geological conditions and degree construction mechanization. In order study vertical compressive performance settlement characteristics ultra-long PHC piles, strain dynamic detections static load te...

OBJECTIVE To investigate the benefit of intensive dynamic exercises in comparison to range of motion (ROM) and isometric exercises in rheumatoid arthritis. METHODS 100 consecutive rheumatoid arthritis patients on stable medication were randomly assigned to (1) intensive dynamic group exercises which included full weight bearing exercises and conditioning exercises on a stationary bicycle whil...

In this research, the variation of ultimate bearing capacity, failure mechanism and deformation pattern of soil beneath two closely square footings have been studied using numerical methods. It is assumed that the adjacent footings are constructed on the surface of sand. The presented numerical analyses are based on explicit-finite-difference code, FLAC3D. The elasto-plastic behavior of soil is...

In this research work, a 3D numerical modeling technique is proposed based on the 3D particle flow code in order to investigate the failure mechanism of rock foundations. Two series of footings with different geometries and areas are considered in this work. The failure mechanism obtained is similar to that of the Terzaghi’s but there is a negligible difference in between. Lastly, one equation ...
