Student bed can also be understood as a phenomenon eccentric compression axial compression at the same time withstand a lateral bending takes all the above axial compression and eccentric compression should thousand members are short and thick for the. For comparison sewing long straight rod member to the way that will not stick in a so-called pressure stability than the forces. That is, the member does not depend on the ability to allowable stress, but depending on the stability, i.e., depending on the member to maintain its original geometry and position of the situation. Stability of the forces is more complex plants Luohe double bunk in the furniture does not have to make a detailed analysis of the structure, only by members of different sewing length ratio. To calculate the length of a double bunk member, the member section of the inertia radius, is the radius of the circular cross-section, a rectangular cross section to take a small side half) p-value look-up table. Allowable stress is calculated by multiplying the p-value that was allowable stress stability. The total pressure; magic that was divided by the allowable stress-sectional dimensions of the excluded members want. Higher allowable stress, etc., but the use of sewing long after the gold member, often enough stability, so empty metal tubular member is always made to ensure its stability: metal materials such as steel. In fact, the only member of axial pressure to bear alone is rarely the case, often playing by the district to consider the issue of its eccentric, long straight bar Gang members consider its stability. Bunk beds in the innovative application of information technology with the construction of schools and social development, the campus network Luohe double bunk Which is good, the popularity of computers, students' daily learning activities have also changed. Library, study room is no longer the only place where students learn. Students can find information on the Internet in the bedroom, using the Internet to learn.

For the contradiction between the student apartment living environment and the needs of the residents currently living and bunk bed process problems, bunk beds should be made functional innovation, adding new features, optimizing the structure designed to better meet the needs of students Life needs. Increase the storage capabilities of small student apartment living area of ??personnel, so most people feel crowded. Bunk bed in the bedroom space as the largest furniture should have some storage capacity to ease tensions space.
