Piled Raft Design Approach for a High Rise Building on Tithal Road, Valsad, Gujarat
Abstract: ABSTRACTThe piled raft foundation has been efficiently used for the foundation of high rise structures. A typical high rise building generally imparts higher load on central core area due to existence of lifts, elevators and shear walls, comparison to the edge area. The shallow foundation may not control the settlement and the pile foundation cost may be expansive for the foundation of high rise structures. The piled raft foundation can …

Computation of Different Stresses Acting on Cantilever Beam Using Hyperbolic Shear Deformation Theory
Abstract: The shear deformation effects are more significant in the thick beams. The classical beam theory (ETB) is based on Bernoulli-Euler hypothesis and the classical plate theory (CPT) is based on Kirchhoff’s hypothesis. The shear deformation effects are more pronounced in the thick beams when subjected to transverse loads than in the thin beams under same loading condition. These effects are neglected in elementary theory of beam (ETB). In order to …

Is tibial expert nailing biomechanically more stable compared to intramedullary nailing for tibial fractures?
Abstract: Background: Fractures of the tibia and fibula are relatively common and have been recognized as serious and debilitating injuries, because its surface is subcutaneous throughout most of its length, open fractures are more common in the tibia than in any other major long bones. To avoid complications of operative treatment in association with these characteristics of the tibia, intramedullary nailing has been widely introduced for the tibial diaphyseal fractures, and …

Biomechanical comparison of Schanz screws placement modes-how can stability by external fixation be raised?
Abstract: AbstractBackground: At present, external fixators are being used widely in open fractures of the long bones and also accepted as a temporary skeletal stabilization even in closed fractures. Therefore, it is essential to increase the stability which is provided by those devices for good outcomes. We hypothesized prior to the study that the greater is the distance between the Schanz screws inserted in each fracture fragment, the higher is the …

Comparison of Lateral and Medial Plate Fixations of Talar Neck Fracture: A 3D-Finite Element Analysis
Abstract: Background: Talar neck fractures are rare, but challenging injuries, because the bone has unique anatomy, and its blood supply makes it difficult to stabilize the fracture and is likely to cause posttraumatic or postoperative complications. Thanks to development of appropriately sized plates, outcomes of plate fixation of talar neck fractures have been improved compared with screw fixation. Although some studies have demonstrated no difference between screw only fixation and screw-plate …
