Critical Proof Load for Proof Load Testing of Concrete Bridges based on Scripted FEM Analysis

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Steel versus Steel-reinforced Concrete Bridges: Environmental Assessment

Bridge material selection has traditionally been b~ed on e.ngineering and economi~ criteria. With the increasing interest of the public, industry, and government m sustainable:: development, en~lronmental. assessment in construction is becoming more important. However, we need metrtcs and data on deSign alternatives for effective decision making. In this paper, we present results of a life cycl...

Pullout Load Analysis of Reinforced Concrete Anchor Shafts

In this paper, results obtained in both conventional and finite element analysis of straight and belled anchor shafts subjected to a pullout force are presented. In numerical analysis, it is assumed that no drainage takes place during the anchor pullout. Comparisons between two conventional methods of analysis for ultimate pullout load and the results obtained by the finite element analysis are...

Calibration of Load and Resistance Factors for Reinforced Concrete

Current approach for designing of reinforced concrete members is based on the load and resistance factor. However the load and resistance parameters are random variables, the constant values have been designated for them in the designing procedure. Assuming these factors as the constants, will be led to the unsafe and uneconomical designs. Safe designing of structures requires appropriate recog...
