This paper presents the effectiveness of strengthening slab–column connections against punching shear failure with near surface–mounted (NSM) carbon fiber–reinforced polymer (CFRP) bars. The experimental program consists preparing and testing eight samples, two control, six strengthened samples. main variables experiment are layout cross-sectional area CFRP results show that NSM increases ultim...

In the case of problematic soils and tall buildings where the design requirements cannot be satisfied merely by a raft foundation, it is of common practice to improve the raft performance by adding a number of piles so that the ultimate load capacity and settlement behavior can be enhanced. In this study, the effect of spatial variability of soil parameters on the bearing capacity of piled raft...

The prediction of the ultimate bearing capacity of the pile under axial load is one of the important issues for many researches in the field of geotechnical engineering. In recent years, the use of computational intelligence techniques such as different methods of artificial neural network has been developed in terms of physical and numerical modeling aspects. In this study, a database of 100 p...

Growing human population has caused the increase in the tempo of construction activity world wide.Since new techniques are either available or constantly emerging the sites which have been deemed unsuitable are being put to use for the construction of new and challenging structures. The foundations for the residential buildings in paddy fields and marshy land with water table near the ground le...

Strengthening of reinforced concrete (RC) columns is needed when the actual load-carrying capacity does not reach required level due to either structural deterioration or increasing acting loads. This experimental study aims evaluate strengthening effect on eccentrically-compressed RC using Carbon fiber polymer (CFRP) sheets, that confine around column cross-section. Three specimens with same g...

This paper presents the results of a parametric study of the flexural behavior of continuous concrete members prestressed with external tendons. The behavior at ultimate limit states is evaluated. A nonlinear analysis model, based on the three dimensional finite element method, ANSYS computer program (10.0) was used. The nonlinear material and geometrical analysis were adopted. The results obta...

Abstract The performance of textile reinforced concrete composite panels (TRCCPs) under the action pseudo-static load up to collapse was evaluated. test TRCCPs axial and transverse loading conducted, results were compared with those for steel wire mesh reinforced-concrete (SMRCCPs). Ceram-site utilized as panel matrix owing its lightweight insulation characteristics. ultimate bearing capacity, ...

The field of quantitative evolutionary design uses evolutionary reasoning (in terms of natural selection and ultimate causation) to understand the magnitudes of biological reserve capacities, i.e. excesses of capacities over natural loads. Ratios of capacities to loads, defined as safety factors, fall in the range 1.2-10 for most engineered and biological components, even though engineered safe...
