  • Các kỹ sư sử dụng ngày một nhiều các phần mềm để thiết kế móng bè như móng mềm để tiết kiệm bê tông. Thay vì dùng khả năng chịu tải của đất, các phần mềm thường yêu cầu khai báo tính chất được gọi là mô đun phản lực nền, tại sao tính chất này của đất là cần thiết, bài báo "Mối tương quan giữa khả năng chịu tải của đất (Soil Bearing Capacity) và mô đun phản lực nền (Modulus of subgrade reaction)" này sẽ giải thích ý nghĩa của các hệ số này và mối liên hệ giữa chúng.

  • This research shows the influence of pile cap on bearing capacity of pile foundation, especially pile groups of shaft resistance. Using PLAXIS-3D FOUNDATION sofware to simulate a actual application with 4 piles in groups and assumption for 7 stiffness modulus of soil under pile cap. The output calculation expresses that in both the cap and the pile carrying the load. The cap is necessary to spread the vertical and horizontal loads and any overturning moments to all the piles in group and transfer load to soil underneath.

  • In this paper, the ultimate load capacities of shell foundations on unreinforced and reinforced sand were determined by laboratory model tests. A series of loading tests were carried out on model shell footing with and without single layer of reinforcement. The tests were done for shell foundation at different shell embedment depth and subgrade density. The results were compared with those for flat foundations without reinforcement. The model test results were verified using finite element analysis using program PLAXIS.

  • This article reviews the current status of the market for catastrophic risk (CAT) bonds and other risk-linked securities. CAT bonds and other risk-linked securities are innovative financial vehicles that have an important role to play in financing mega-catastrophes and other types of losses. The vehicles are especially important because they access capital markets directly, exponentially expanding risk-bearing capacity beyond the limited capital held by insurers and reinsurers.

  • The application of prestressing steel is restricted in highly corrosive environment area due to corrosion of prestressing steel, which leads to reduction in strength and it may cause sudden failure. Carbon textile is considered as an alternate material due to its corrosive resistance property, high tensile strength and perfectly elastic. In this study, an experimental investigation was carried out to study the flexural behavior of prestressed and non-prestressed carbon textile reinforced concrete plates.

  • In hybrid structures, material layers of different mechanical properties are integrated to increase bearing capacity. When the difference in mechanical properties or thickness of the material layers is very large, debonding usually occurs along the interface between the two layers. This study uses a homogenization procedure combined with asymptotic algorithm applied on weaker/thinner materials to determine the interface stiffnesses for such structures. All the material layers and the interface are assumed to be linear elastic.
