Expansive soils are found in many parts of the world that especially arid and semi-arid regions. They have caused several damages lightweight structures for decades. For this reason, a more suitable foundation type should be selected designed built on these soils. example, application belled shaft at expansive soil layer is preferable method practice. However, one worst cases design accepted sw...

hadamard (or complete $cat(0)$) spaces are complete, non-positive curvature, metric spaces. here, we prove a nonlinear ergodic theorem for continuous non-expansive semigroup in these spaces as well as a strong convergence theorem for the commutative case. our results extend the standard non-linear ergodic theorems for non-expansive maps on real hilbert spaces, to non-expansive maps on had...

Expansive soils shrink and swell with drying wetting cycles. The shrink-swell capacity of expansive can result in differential movement beneath foundations which is a very common cause foundation problems. Ribbed slab, often called waffle one the efficient inexpensive solutions for use under light structures resting on soils. This paper presents numerical analysis that used to calculate displac...

Presence of swelling soils under the foundations of civil engineering structures particularly lightly loaded structures has caused serious damages around the globe due to their differential up heaving. In this paper, based on the results of swell tests on bentonite mixed clay, correlations for predicting the swelling parameters (i.e., swell potential and swell pressure) have been proposed. Mixi...

Abstract Expansive soils are referred to as swelling a result of changes or modifications in the water content soil. This study aims determine how addition fly ash affects value expansive soil's free compressive strength well curing period that has been stabilized with ash. Variations were made by 5%, 10%, 20%, and 25% times 0 days, 7 14 28 days see adding affected Free Compressive Strength Val...
