Abstract:
During a research study conducted in 2013, using data from the 2008 OSHA Data Initiative (ODI), several research findings became apparent about safety statistical data provided by OSHA. These research findings included analysis of mishaps by organizational type, ownership, annual revenue and numerous other organizational wide variables that were studied. These findings serve as the basis for conclusions that will be presented, primarily focused on the statistical data meanings and the findings that have relevance to the safety within the industrialized world

Abstract:
Managing risks in construction projects have been recognized as a very important management process in order to achieve the project objectives in terms of time, cost, quality, safety, and environmental sustainability. However, thus far most research has focused on some aspects of construction risk management rather than using a systematic and holistic approach to identify risks and analyze the likelihood of occurrence and impacts of the risks. Aims to identify and analyze the risks associated with the development of construction projects from project stakeholder and life cycle perspectives. This research also found that risks spread through the whole project life cycle and many risks occur in more than one phase, with the construction stage as the riskiest phase, followed by the feasibility stage. This research would conclude that clients, designers and government bodies must work cooperatively from the feasibility phase onwards to address potential risks in time, contractors and subcontractors with robust construction and management knowledge must be employed early to make sound preparation for carrying out safe, efficient and quality construction activities. A building project is a process where each activity and phase include different risks that should be handled by the project participants. Nowadays, the building market is developing very fast and it is important to deliver the project to the client on time and within the budget, each decision made in the conceptual design phase can have an impact on other phases and bring consequences that could be negative for the building project, assignments in a building project, such as conceptual, preliminary, design development and construction execution has performed by a project participants according to the role, can also be referred to a project or a project task, because it contains the parts that the project teams work on within a company. The risks related to critical events in the project tasks are managed by the project participants according to their responsibilities defined in the contract form. The risks managed in the project tasks are an integral part of the risk existing in the building projects to complete on time and within the budget

Abstract:
The structural system of the resilient prestressed steel frame with intermediate column contain friction damper and the typical details of the intermediate column containing friction dissipating damper was put forward for researching the resilient capacity to large-span prestressed steel structures. An eight-story prototype structure was designed and a pseudo-dynamic test of the first story plane frame containing the intermediate column with friction damper subjected to El-Centro ground motion for PGA= 0.07g, 0.2g, 0.4g, 0.51g, 0.62g, 0.8g, and 1.0g was conducted. In this paper, the numerical simulation toward the pseudo-dynamic test was carried out by adopting finite element analyzing software Abaqus. The hysteretic curves, the cable forces, the self-centering capacity, the gap-opening, the structural stiffness, the strain variation as well as the energy dissipating capacity were compared with those from the test and analyzed. The results show that both the results achieved from the test and the numerical simulation were in coincidence; the intermediate column containing friction damper not only increase the structural stiffness but enhance the energy dissipating capacity of the structure. The main structure still remains elastic except the reinforcing plate of the beam flange and the foot of the column. The story shear force-displacement hysteretic curves of the first story frame was achieved which presented to be in shuttle shape. The loss of the cable force in steel strand is very little after the test which indicates that the anchorage method of the prestressed steel strand is reliable as well as the structure possess an out-standing self-centering mechanism and resilient capacity to resist earthquakes and aftershocks with large magnitudes.
