  • Rural facilities need to be changed to be industrialized and long span structures due to accelerating aging of the rural population. In this study, the optimized structure was developed by applying Pre-Engineered Building System using the tapered member to make that the Korea standard green house has a long span. When considering design load, reasonable values were adapted by reviewing existing design codes. As a result, applying pre-engineered building system was efficient in structural system that has span longer than 16 m. And it was concluded that the increase with the longitudinal span from 4 m to 12 m was more efficient in aspect of steel amount.

  • In December 2005, one(A) of the two pre-engineered warehouse buildings in the port of K City of Korea was completely destroyed and the other(B) was seriously damaged to be demolished. Over-loaded snow and unexpected blast of wind were the causes of the accident and destructive behavior was brittle fracture caused by web local buckling and lateral torsional buckling at the flange below rafter. However, the architectural design technology of today based on material non-linear method does not consider the tolerances to solve the problem of such brittle fracture. So, geometric non-linear evaluation which includes initial deformation, width-thickness ratio, web stiffener and unbraced length is required. This study evaluates the structural safety of 4 models in terms of width-thickness ratio and unbraced length using ANSYS 9.0 with parameters such as width-thickness ratio of web, existence/non-existence of stiffener and unbraced length. The purpose of this study is to analyze destructive mechanism of the above-mentioned two warehouse buildings and to provide ways to promote the safety of pre-engineered buildings.

  • With the improvement of the quality of construction materials and the development of construction technologies, large-scale long-span steel frame buildings have been built recently. The P.E.B system using tapered members is being employed as an economically-efficient long-span structure owing to its advantage of being able to distribute stress appropriately depending on the size of sectional areas of members. However, in December 2005 and in February 2014, P.E.B buildings collapsed due to sudden loads such as snow loads and wind gusts. In this study, the design and construction of the P.E.B system in Korea were analyzed and its structural safety was evaluated using the finite element analysis program to suggest how to improve the P.E.B system in order to promote the efficient and rational application of the system.

  • Structural design of most nonprismatic Pre-Engineered Building Systems (PEBS) is performed using optimizing software developed in foreign countries. In this study, a structural optimizing software for the design of 3-D structures of nonprismatic PEBS is developed according to the allowable stress design method of AISC2005 and KBC. Optimizing structural design with nonprismatic members is carried out by repeating the process of structural analysis and member design to minimize the weight of a structure. According to the optimizing design results of 2-D and 3-D structures with nonprismatic members, there are considerable steel savings in designing structures with nonprismatic H-shaped built-up sections rather than with H-shaped rolled sections. When H-shaped built-up sections were used, the weight of the structural steel was reduced when AISC2005 specification rather than AISC1898 was used in the design. It is therefore concluded that utilizing the new AISC2005 specification is safer in preventingweb buckling because the height of a member is designed to be small despite some differences depending on the structural type.

  • The pre-engineered building(PEB) construction has been gradually applied to single story buildings as a practical and efficient alternative to conventional buildings. However, there has been a few structure collapse due to suddenly excessive load. Although a structure design requires accurate and professional skills, the PEB system tends to be designed simply because of complexation of structural analysis for connections. This paper shows the finite element analysis(FEA) using ABAQUS software on bolted connection which was previously tested. The FEA condignly simulated the behavior of bolted connection in PEB system and was in close agreement with experimental results. Then the stiffness reduction factor of the bolted joints that can be used in the actual design is presented through the analysis of the joint parameters.

  • In domestic construction industry, now demand for airport facilities, gymnastic facilities, mass meeting facilities, sales facilities is increasing. Because of this, demand for huge space is also increasing. In making huge space, existing PEB(Pre-Engineered Building) and Pipe Truss, As span is lager and larger, steel weight is increasing and hard to apply for large span. For solving this problem, Many program was proposed, and in that Space Frame was rising. But in domestic construction there are very rare practical use for Space Frame. In this study, we wish to introduce Space Frame that has several advantages in construction expense, construction time, constructibility and also with analyzing example for applying Space Frame, wish to investigate characteristic of Space Frame. Go forward better, through comparison of other different old method and basic character of Space Frame, confirm advantage of Space Frame that have infinite development possibility and revitalize the Space Frame in domestic study and further more wish to raise practical use for Space Frame.

  • PEB system is more economical when compared with structures commonly used Hot rolled and welded light H-beam was introduced in the Standard Livestock Housing. This study suggested more economical technology for structural design by the reduction of live load, relief of deflection limit and reduction of importance factor. And, when applying wind Load as a result of examination with Low Rise Building Systems Manual considering open model, we can know that when the wind load is big, enclosed model is more stable than open model. In short, Suggesting more economical model and providing the method to reduce natural disaster, by the application of PEB system and the development of technology for structural design, are considered to strengthen the competitive power of farmhouse.
