Bearing capacity of soil is an important factor in designing circular footing. It directly related to foundation dimensions and consequently its performance. The calculations for obtaining the bearing a needs many varying parameters, example type, depth foundation, unit weight soil, etc. In this work, comparison between values footing on gypseous before after improvement determined by two diffe...

In shallow foundations, the third bearing capacity factor, N, has been found to show a decreasing tendency with increasing the foundation size. It is supported by experimental observations and related mainly to stress level dependent nature of the soil. On the other hand, the bearing capacity is often obtained theoretically without consideration of the foundation vertical displacements. In thi...

Several deficient steel structural members require to be strengthened all over the world. In this article, horizontal defects were generated at three locations (top, middle, and bottom) on the middle element and the middle of the side element. Consequently, the effects of the location of such defects on axial behavior of Carbon Fiber Reinforced Polymer (CFRP) strengthened steel Square Hollow Se...

In this paper, five sets of multi-bolted joint shear tests are designed to study the effect bolt middle distance on bearing performance joints, and analyze failure modes specimens. The main conclusions as follows: For M10 bolts (grade 8.8) bamboo curtain plywood connections. When spacing increases 50mm, ultimate capacity nodes tends be stable; initial stiffness joint, has no obvious joint. Howe...

We evaluated mechanical properties (first matrix cracking stress, strength, and work-of-fracture) of Nicalon-fiber-reinforced silicon carbide matrix composites with three different fiber lay-up sequences (0"/20"/60", O0/4Oo/6O0, and 0"/45") at various temperatures from room to 1300°C. Up to 1200"C, ultimate strength and work-of-fracture for the 0"/40"/60" and 0"/45" composites increased, but th...

Numerical modeling was carried out to investigate the responses of suction bucket foundations under vertical cyclic loading. Numerical results were compared with centrifuge experiment results. Before the capacity of the model suction bucket to resist cyclic loading could be investigated, the static pullout capacities had to be determined. The buckets with different aspect ratio are investigated...

This study examines the capability of the Relevance Vector Machine (RVM) and Multivariate Adaptive Regression Spline (MARS) for prediction of ultimate capacity of driven piles and drilled shafts. RVM is a sparse method for training generalized linear models, while MARS technique is basically an adaptive piece-wise regression approach. In this paper, pile capacity prediction models are developed...
