Square columns

The effectiveness of FRP in retrofitting/strengthening existing steel reinforced concrete (SRC) structures has been widely recognized. This paper compares the performance of SSRC columns without and with different CFRP bands to examine the effect of the location and width of CFRP bands on the performance of CFRPBC-SSRC.

The paper presents experimental results and structural analysis of reinforced concrete (RC) columns made of recycled aggregate concrete (RAC) and natural aggregate concrete (NAC) under concentric compressive load. The ratio of recycled aggregates in mixture (i.e, replacement ratio, r in %) was 0, 50, and 100% by mass, where r = 0% corresponding to NAC.

This paper presents a numerical analysis of the seismic behavior of square concrete filled steel tubular (CFST) columns. Finite element analysis (FEA) models in ABAQUS software were used to simulate a series of columns subjected to axial compression and cyclic lateral loading. The CFST columns were simulated using nonlinear tri-dimensional (3-D) finite elements for the infilled concrete, and nonlinear two-dimensional (2-D) finite elements for the steel tube.

Medial open-wedge high tibial osteotomy (HTO) is an effective and safe treatment method for medial osteoarthritis of the knee. However, unintended changes in the posterior tibial slope (PTS) may occur.

In the two-coupled distillation column process, keeping the tray temperatures within a specified range around their steady state values assures the specifications for top and bottom product purity. The two-coupled distillation column is a 4 Input/4 Output process. Normally, control engineers decouple the process into four independent loops. They assign a PID controller to control each loop. Tuning of conventional PID controllers is very difficult when the process is subject to external unknown factors.

A Skill Based Matrix provides a pictorial summary of the skill areas in which employees are expected to cross-train. Each column represents a process (or step in a process) and each row is a level of difficulty. Each “square” is called a skill block. A group of skill blocks provide the employee with a skill path to follow. Please consult. To consult more other training materials, please consult at Bộ tài liệu Đào tạo nội bộ Doanh nghiệp

Setting Equation (6) equal to zero and solving for P also provides the level of population at the turning point as referred to above. Our results therefore clearly suggest that the marginal impact of population on sulfur dioxide emissions is an increasing function of the level of population i.e., the greater the level of population, the greater the envi- ronmental impact of each additional unit of population. As a next step, column III reports results from the model that examines the role played by the age structure of the population.

The simple linear population term is insignificant, however. In column II we investigate whether this is due to a non-linear effect of population size. The results suggest that this is indeed the case as both the linear and the squared population terms are statistically significant. This indicates that emissions experience a U-shaped relationship with population. Differentiating our estimated equation with respect to population and setting this equal to zero allows us to identify the turning point level of population: The estimated turning point is at around 5.4 million people.

As a next step, we investigate whether the emission elasticity of the population variable changes with population size. Our second model, for which results are reported in column II, therefore allows for a non-linear relationship between population and pollution emissions by including population squared (POP2 ). The linear term becomes statistically insignifi- cant, which suggests that the relationship is not quadratic. 4 We therefore only include the linear population term in the estimations that follow.
