the present study focuses on the performance of precast concrete beam-column dowel connections subjected to cyclic loading by conducting experiments. in this study, one-third scale model of two types of precast and a monolithic beam-column connection were cast and tested under reverse cyclic loading. the precast connections considered for this study is a beam-column connection where beam is con...

Change in the mechanism of post corrosion bond behavior was investigated a previous experimental study by analyzing deformations concrete using digital image correlation (DIC). Using their DIC data, this focuses on local strain non-uniformity reinforcing bar during uniaxial tensile test due to effect rib height reduction and layer. The results show that, below tip is higher than that flat part ...

This note reexamines Spector’s remarkable computational interpretation of full classical analysis. Spector’s interpretation makes use of a rather abstruse recursion schema, so-called bar recursion, used to interpret the double negation shift DNS. In this note bar recursion is presented as a generalisation of a simpler primitive recursive functional needed for the interpretation of a finite (int...

According to the report of the United Nations, it is said that two-third of world population would be influenced by water shortage before 2050. To use fresh water effectively, the usage of seawater in concrete industry seems imperative. However, the usage of seawater as concrete material is prohibited in almost all the standards or specifications around the world. In this article, the usage of ...

Abstract—Recently, the climate change is the one of the main problems. This abnormal phenomenon is consisted of the scorching heat, heavy rain and snowfall, and cold wave that will be enlarged abnormal climate change repeatedly. Accordingly, the width of temperature change is increased more and more by abnormal climate, and it is the main factor of cracking in the reinforced concrete. The crack...

Transportation is an important part of modern community life as well as one of the largest sources of greenhouse gas emissions in urban communities, the population growth of which can increase transportation capacity. Monorail systems are relatively new rail transportation systems which are currently being designed and constructed in different countries. We have applied the Intergovernmental Pa...

this document provides feasibility study of using treated domestic wastewater in concrete mixing. today, concrete is one of the most important construction materials. from first time that concert was used in construction materials, always the drinkable water used for concrete mixing water. domestic wastewater contains about 400 ppm of organic materials. after the treatment of wastewater, concen...

this paper presents a cuckoo optimization algorithm (coa) model for the cost optimization of the one-way and two-way reinforced concrete (rc) slabs according to aci code. the objective function is the total cost of the slabs including the cost of the concrete and that of the reinforcing steel. in this paper, one-way and two-way slabs with various end conditions are formulated as aci code. the t...
