อาคารสำเร็จรูปครึ่งทรงกลมจากโครงสร้างเหล็กแบบถอดประกอบง่าย

The objectives of this research are to develop the structure to create the knowledge of construction technology to test the properties to construction the prototype building and to transfer the technology of hemisphere pre-engineered building with easy assembly steel structure type. The load and resistance factor design (LRFD) method was used to design the structure by regarding the strength material type construction and deconstruction step and cost. From the design the prototype of hemisphere pre-engineered building (only the frame structure) was construction with 5 meters of diameter 3.5 meters of height 19.635 square meters of useful space 200000 Baht of material cost (10186 Baht per square meter for all materials) 27 hours or 3 days of construction period. According to the modular coordination system this hemisphere pre-engineered building cans construction and deconstruction fast especially when apply to help disaster victims. After tested the structure that the calculation value of safety factor (S.F.) is 1.76. The envelope of this building used the ratio of Portland cement type 1: fine sand: coconut fiber: waterproofed liquid: tap water which equal to 1:3: 0.1: 0.02: 0.5 by weight and reinforced by round bar and wire mesh steel. According to the testing the building-envelope properties are following: density 1582 kg/m3 thermal conductivity coefficient 0 .3 7 1 watt/m.Kelvin water absorption 1 7 .3 1 % compressive strength 118.47 ksc and bending strength 28.88 ksc. Moreover these results can register the copyright and draft the research paper to transfer the technology for target group.

Cost of safety system in building construction
Cost of safety system in building construction

The goal of this study is to study the cost of safety system in building construction by studying multipurpose building with durable goods project. The cost of safety system in building construction is divided into two categories are the safety measure cost and the safety program cost in construction. From the study it is found out that the value of safety measure cost is approximately 1.85 % of a project cost and the value of safety program cost is approximately 0.98 % of a project cost. To sum up the cost of safety system in building construction is approximately 2.83 % of a project cost .Moreover the study found out that the safety measure cost is higher than the safety program cost about 1.88 as much. From the data of this study it can be used as the guideline in estimating the cost of safety system in building construction for the future project.
