Column Shortening of SRC Columns Considering the Differential Moisture Distribution

Reduction of Differential Column Shortening in Tall Buildings

Numerical and Experimental Investigations on the Behavior of Steel-reinforced Concrete Columns Subjected to Eccentric Loading

Steel-reinforced concrete (SRC) columns, which are classified as composite columns, became the most widely used in recent years; because of their extensive advantages over the reinforced concrete and the steel columns. In this paper, the ductility index and its influential factors were explored to investigate the behavior of SRC columns. A straightforward approach was then proposed by establish...

Effects of Column Shortening in Tall R.c. Buildings

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...

The Effect of Water Quality and Irrigation Methods on Moisture and Salinity Distribution of Soil

Current study was carried out with aim to evaluate the effect of pressurized irrigation methods and furrow irrigation method with municipal effluent on distribution of salinity and moisture in the soil profile. The experimental study was designed by split plot layout with three irrigation methods including furrow, surface drip (SD) irrigation and subsurface drip irrigation (SSD) and two water q...

Response Spectra for Differential Motion of Columns

The common modeling assumptions in analyses of structural response considering the effects of soil-structure interaction are discussed, as well as their consequences. Issues such as spatial variability of strong ground motion and flexibility of building foundations are specifically addressed. Results are shown for the case when spatial variability is considered, but inertia interaction and kine...
