Abnormal loads can produce localized damage that eventually cause progressive collapse of the whole reinforced concrete (RC) structure. This might have devastating financial repercussions and numerous severe casualties. Numerical simulation, using finite element method (FEM), consequences abnormal on buildings is thus required to avoid significant expenses associated with testing full-scale sav...

Textile reinforced mortar (TRM) is mainly used for strengthening of existing structural members whereas, on the other hand concrete (TRC) a technology implied in construction new enhancing behaviour. Application TRM tension zone (RC) slabs to improve flexural capacity has been investigated by many researchers past. However, effectiveness textile fabrics, as internal reinforcement RC slab (TRC t...

This article presents the advantages and limitations of a recently developed Ultrasonic Guided Wave Leakage (UGWL) method in comparison to well-known Half-Cell Potential (HCP) their ability detect corrosion reinforced concrete (RC) bridge decks. research also establishes correlation between UGWL data chloride content RC slabs. Concrete slabs submerged 10% NaCl solution were monitored using both...

Data collected from shake table tests of two, approximately one-third scale, two story flat plate frames utilizing shear reinforcement, as well as data from prior tests, were evaluated to assess the inter-story drift ratios when punching failures occur for reinforced concrete and post-tensioned slab-column connections with and without shear reinforcement. The drift ratios at punching for the sh...

Paper presents the main principals in designing wood-lightweight concrete composite floor structures using FEM models. All design-related analyses are performed by means of the FEA COSMOS/M program. Paper emphasises some important details in FEM model design (how to choose appropriate finite elements for different types of materials, how to connect concrete slab and timber beams to work togethe...

In this paper, we study gradient Ricci expanding solitons (X, g) satisfying Rc = cg +Df, where Rc is the Ricci curvature, c < 0 is a constant, and Df is the Hessian of the potential function f on X . We show that for a gradient expanding soliton (X, g) with non-negative Ricci curvature, the scalar curvature R has at least one maximum point on X , which is the only minimum point of the potential...

Abstract Tectonic processes control hot spring temperature and geochemistry, yet how this in turn shapes microbial community composition is poorly understood. Here, we present geochemical 16 S rRNA gene sequencing data from 14 springs contrasting styles of subduction along a convergent margin the Peruvian Andes. We find that tectonic influence on geochemistry composition. Hot flat-slab back-arc...
