This paper is intended to show how the degree of fixity method employed, permits the clear understanding of the P-Δ effect and the determination of the P_(cr) for Column and frames, without making reference to the different concepts of restrained sway or free sway. The method reveals some advantages over the ACI method. It is also contrasted with other method using examples and analyses.

There is a critically structural problem of scaffolding system when one of scaffold columns is remove to be used as a gangway for their temporary office in the structure before finishing all such as an apartment or office building. This is not used to checking to structurally checking at a construction site. This study is to find out which system at a site will be more effective and low-cost-high effectiveness of aluminum ladder, timber ladder, ?1/2 inch steel pipe truss with a type of concave, convex warren truss ladders. Theses are structurally tested with horizontal set as a truss type with 1.8 meter long. Concentrated load has been loaded at the upper center of the system and checked its strain at the bottom center, using aluminum-use strain gage and steel-use gauge have been attached concave warren truss with diameter 1/2 inch has 14% stronger than convex truss. Convex truss has almost same strength as an aluminum ladder truss, it is found out.

There are many countermeasures collected by field experts, safety managers with their subjective decisions, without analysis. Subcontractor does not know which one of those can be more defective countermeasures. More weighted countermeasures should be taken for subcontractor`s economical aspects. But there are almost no measures with useful weight so that subcontractors can select some as they need more effective even though there are not many measures at construction sites. AHP technique has been introduced into the analysis of counter measures for subcontractor. Countermeasures which car collected from field-experienced safety engineers have been weighed with frequency rate saying how many responders selected. And then, they are analyzed by AHP Technique for making out relative important level of the countermeasures, by each step such as Direct, Indirect, Management level, and policy level, quantitatively. AHP level in the study is composed of two stories, not three stories, in order to make respondents easier when they are asked. At least 15-year-experienced expert are asked for AHP questionnaire

Accident prevention plan it a construction site should be analyzed and made with risk evaluation and management, from recent year, in Korea. Accidents occurred in construction site are related to all parties such as owner, main and subcontractor, labour. But analyzing some relationship between main and subcontractor is very important to estimate what risk between then are existed in a site. There are some different aspects concerning with risk management between them. Everywork has its own risk in there, This is the reason why everywork which are made by subcontractor himself should be evaluated for risk level. And main contractor should provide for subcontractor to prevent each risk at the work, all the time.

Accidents that people are fallen or overturn from the stairway have been frequently occurred andseriously injured. it is reported that there are many causes of this kind of accidents. Only physical conditions for the people has been considered in Building code since decade year ago,despite the fact that average height of people has been made higher. Therefore, this study is to find out the new suitable and available dimension of the stairway. Another aspect that we have to consider is to safety design in consideration of not 26cm but morethan 28cm for elementary school and not 26cm but more than 30cm for middle & high school.
