Fiber-reinforced polymers (FRPs) have been widely utilized to improve the seismic performance of deficient reinforced concrete (RC) columns. In recent years, one of the emerging types of FRPs used is basalt fibers. In this study, the performance of existing columns was experimentally examined before and after applying near-surface mounted (NSM) basalt FRP (BFRP) rebars as a retrofitting techniq...

In tall and very tall reinforced concrete buildings, long term column shortening due to creep and shrinkage affects the service life behavior of structural elements. Creep-induced column shortening depends on the axial stress level in the column cross sections and on its evolution in time. For this reason, the construction method and phases must be taken into account as a key factor in defining...

Partially Encased Composite (PEC) column is one of the recent achievements in the field of composite columns. This paper presents a combined experimental and theoretical study on the mechanical performances of six octagonal PEC columns subjected to axial compressive and bending moment loading. The major different between them was the concrete reinforcement details. The parameters studied in the...

This paper investigates the behaviour of hybrid fibre, i.e. a combination E glass and basalt added in reinforced concrete column. A total 6 columns were cast with Conventional Concrete (CC) Hybrid Fibre Reinforced (HFRC) to study structural performance The was made cement, manufacturing sand (m-sand), coarse aggregate as major ingredients. In column, 2% Basalt fibre along E-Glass 1% make HFRC. ...

MATHCAD is a sophisticated computation and presentation tool, which is versatile, easy to use, and accessible. It holds strong potential as a learning aid for education and training. This article demonstrates the use of MATHCAD to supplement and enhance traditional teaching and learning methods both inside and outside the classroom. The paper focuses on the topic of reinforced concrete column d...

Composite RCS building frames integrate reinforced concrete columns with structural steel beams to provide an efficient solution for the design and construction of earthquake-resisting structures. In this paper, an optimization framework is developed for performance-based seismic design of planar RCS moment resisting frames. The objective functions are defined as minimizing the construction cos...

In this study, the behavior characteristics of I beam-to-concrete filled tube (CFT) column connection is studied through experiment and finite element models under the monotonic loading. To validate the finite element modeling, at first, an experimental model is made and experimented. After validation of the finite element modeling, different models were created in the software. The studied par...

Geopolymer concrete can resist fire quite well when compared with conventional concrete. Recent studies to observe the behaviour of geopolymer composite column under effect are very few. In this paper results in terms stress, strain and deformation expressed elevated temperature presented. It was observed that performs better at temperatures than column. This tests performed four which is teste...

A method to predict the column size for displacement based design of reinforced concrete frame buildings with higher target inter storey drift is reported here. The column depth derived from empirical relation as a function of given beam section, target inter-story drift, building plan features and common displacement based design parameters is used. Regarding the high drift requirement, a mini...
