Occupational risk factors, such as awkward posture, repetition, lack of rest, insufficient illumination and heavy workload related to construction-related MMH activities may cause musculoskeletal disorders and poor performance of the workers, ergonomic design of construction worksystems was a critical need for improving their health and safety wherein a dynamic biomechanical models were require...

The unprecedented growth in construction activities have led to speedy consumption of global natural resources like river sand, blue metal, water, and some raw materials like limestone (for producing cement). This study explores the possibility of using Steel-Mesh Reinforced Cementitious Composites (SMRCC) as an alternative to conventional concrete, aiming at sustainability. In order to underst...

This paper presents an animation which simulates construction process by applying tower cranes to assemble shared steel forms in a site of six buildings. Only two sets of steel forms are provided. The animation is simulated based on the length of a cycle .and the number of cycles (a unit period of time) spent for sliding slabs down and moving cranes to next building's location. The first case s...

The potential for monitoring the construction of post-tensioned concrete beams and detecting damage to the beams under loading conditions was investigated through an experimental program. First, embedded sensors were investigated that could measure pre-stress from the fabrication process to a failure condition. Four types of sensors were installed on a steel frame, and the applicability and the...

This paper reports on the North American state-of-the-art in the use of FRP composites in concrete structures. FRP bars have been used as the internal reinforcement in concrete members to replace conventional steel rebars for a host of reasons. The principles for design and construction have been established and proposed to industry by the American Concrete Institute (ACI). The fundamental prin...

The wind turbine foundation serves as a permanent construction in the harsh marine corrosive environment, its anticorrosion design is essential to the safe use of the wind turbine structure. At present, there is a significant controversy over the local corrosion mechanism (such as pitting corrosion, and crevice corrosion) and its diffusion mechanism in the academic circle. In the paper, the Far...

Introduction The nondestructive, in-situ testing of early-age concrete properties is a crucial point for the progress of many construction projects in the building sector. The application of such techniques can establish e.g. the earliest possible form removal from concrete construction elements, thereby opening highways to traffic or releasing prestress from steel reinforcement with greatest e...

Kobe Steel's history of pelletizing plants began when the company built a plant at its Kobe Works in 1966. This paper introduces the history of pelletizing plants, including process outlines and the latest achievements in the construction of plants overseas. In the past, plant owners had focused mainly on the quality of the product pellets and plant equipment, as well as the cost of the plants....

1. Problems Setting One of the tasks of the Construction office of company STOBET Ltd is to create large sheets of paper containing a lot of objects describing a building construction as tables, charts, drawings, etc. For this reason it is necessary to arrange the small patterns in a given long sheet of paper with a minimum wastage. Another task of the company is to provide a way of cutting a s...
