This study carried out comparative seismic performance of reinforced concrete frames infilled by masonry walls with different heights. Partial and fully infilled reinforced concrete frames were modeled for the research objectives and the analysis model for a bare reinforced concrete frame was also established for comparison. Non–linear static analyses for the studied frames were performed to in...

a parametrik investigation was conducted to study the non-linear behavior of precast and cast-in-place reinforced concrete beam-column connections subjected to tabas seismic forces (1979). the behavior of these types of connections in a four stories structure with respect to strength, ductility , stiffness, and bond deterioration at the joint core are presented and discussed. calculation result...

The enhanced structural performance of Reinforced Concrete (RC) columns retrofitted by Fiber Reinforced Polymer (FRP) composite jackets, has been well demonstrated and an increasingly large number of bridge and building columns have been retrofitted with such jackets in the United States and elsewhere. However, seismic damage such as debonding between the jacket and the column that can consider...

This paper presents results of testing 16 specimens, 12 of which as columns under different eccentricities and four as beams under four point loading regime. All 16 specimens were circular in cross section and were made of reinforced concrete. Four specimens served as reference specimens and were just made of reinforced concrete. The next four specimens were wrapped with Carbon Fibre Reinforced...

When an extreme earthquake occurs, it is essential to detect the severe structural damage that affect the structural safety immediately. This paper proposes a method for quick earthquake damage detection/evaluation of reinforced concrete bridge columns. An intelligent sensor unit is developed that captures changes in the natural period of a bridge column by FFT of response acceleration recorded...

Punching shear capacity is a key factor for governing the collapsed form of slabs. This fragile failure that occurs at the slab-column connection is called punching shear failure and has been of concern for the engineers. The most common practice in evaluating the punching strength of the concrete slabs is to use the empirical expressions available in different building design codes. The estima...

Seismic pressures on a reinforced concrete moment-resisting structure are known to create critical and essential regions at the beam-column joints. Beam-column junctions microcosm of whole structure, therefore brittle behavior these points predicts action. Ductile joints ductile Under influence seismic forces, between RC beams columns exposed high shear stresses. Learn more about performance fi...

There can be many reasons for engineers to place the footings near a slope such as leakage of suitable sites or architectural considerations. One of the approaches to increase the amount of bearing capacity, especially in soft soils, is adding stone columns to the soil. In this research, the behavior of a strip footing placed near a stone column reinforced clayey slope was investigated. For thi...
