ATTEMPTS ON SEISMIC RETROFITTING METHOD OF LEANING-TYPE RETAINING WALL USING SOIL IMPROVEMENT PILES

Seismic stability of reinforced-soil wall by pseudo-dynamic method

Determination of the internal stability of reinforced soil walls under earthquake conditions is an important part of seismic design. The horizontal method of slices is used for determining internal stability or for tieback analysis of the reinforced soil wall. A pseudo-dynamic method is adopted in the present analysis, which considers the effect of phase difference in both the shear and primary...

Retrofitting Of RCC Piles By Using Basalt Fiber

Retrofitting works are immensely essential for deteriorated and damaged structures in Engineering and Medical fields, in order to keep, or return to, the originality for safe guarding the structures and consumers. In this paper, different types of methods of retrofitting review notes are given based on the experimental, numerical and analytical methods results on strengthening the Reinforced ce...

OPTIMAL DESIGN OF CANTILEVER RETAINING WALL USING DIFFERENTIAL EVOLUTION ALGORITHM

Optimal design of cantilever reinforced concrete retaining wall can lead considerable cost saving if its involvement in hill road formation and railway line formation is significant.  A study of weight reduction optimization of reinforced cantilever retaining wall subjected to a sloped backfill using Differential Evolution Algorithm (DEA) is carried out in the present research.  The r...

A Superelastic Retrofitting Method for Mitigating the Effects of Seismic Excitations on Irregular Bridges

Irregularities in bridge pier stiffness concentrate the ductility demand on short piers; while not operating on the longer and more flexible ones. The existence of non-uniform, ductility demand distribution in bridges significantly influences seismic response. As such, this paper proposes a new approach for balancing the ductility demand in irregular bridges by utilizing shape memory alloys (SM...
