Center for By-Products Utilization EVALUATION OF HIGH STRENGTH CONCRETE BY THE BREAK-OFF METHOD

The Break-Off method is the most recent development in in-place concrete strength testing. In this method, the force required to break-off an in-place concrete cylinder 2.17 in. (55 mm) in diameter and 2-2/4 in. (70 mm) long, is related to the compressive strength of the concrete from a predetermined calibration curve developed for this concrete mix. The reliability of the BreakOff method to te...

Numerical Analysis Research of Jacking Method with the Rectification on Steel-Concrete Buildings

This paper first analyzes the tilting reasons of a steel-concrete building in Zhangjiakou city in China. Then, a jacking rectification method which combines the pie-cutting method and the excavation of stress release trench was put forward. This analysis method uses the three-dimensional numerical simulation for soil settlement and vertical displacement and internal force of upper structure in ...

Numerical Analysis of Concrete Crash Barriers

Reinforced concrete crash barriers used in road traffic must meet a number of criteria. Crash barriers are laid lengthwise, one behind another, and joined using specially designed steel locks. While developing BSV reinforced concrete crash barriers (type ŽPSV), experiments and calculations aimed to optimize the shape of a newly designed lock and the reinforcement quantity and distribution in a ...

The Green Element Method for Numerical Well Test Analysis

To use pressure transient test data in computerised methods for integrated reservoir charcterisation numerical simulations of the well tests are typically required. Numerical artifacts occurring in the simulation must be avoided as much as possible so that they do not adversely affect the reservoir characterisation. This work explores the advantages of a hybrid boundary element method known as ...
