【摘要】：結(jié)構(gòu)效率系數(shù)基于結(jié)構(gòu)效率影響因素提出,為結(jié)構(gòu)分析提供一個定量的指標(biāo)。綜述了現(xiàn)有的適用于高層建筑結(jié)構(gòu)的結(jié)構(gòu)效率系數(shù),包括:1基于軸向變形貢獻(xiàn)率的結(jié)構(gòu)效率;2結(jié)構(gòu)整體彎曲剪切變形比s系數(shù);3基于剛度折減的桁架效率系數(shù)E_f;4基于構(gòu)件應(yīng)力的材料效率指數(shù)MEI_c;5基于結(jié)構(gòu)布置的結(jié)構(gòu)效率系數(shù)。對比了各系數(shù)的適用范圍、優(yōu)化準(zhǔn)則、優(yōu)化層次、作用和優(yōu)缺點,并對值得進(jìn)一步研究的問題做出展望。結(jié)構(gòu)效率系數(shù)可促進(jìn)結(jié)構(gòu)體系的改進(jìn)和創(chuàng)新,又可用于工程設(shè)計,為結(jié)構(gòu)優(yōu)化設(shè)計提供有效的指導(dǎo)。
[Abstract]:The factors affecting the efficiency of the structure efficiency coefficient is proposed based on the structure, provide a quantitative index for structural analysis. Summarizes the suitable for the high-rise building structure efficiency coefficient, structure efficiency: 1 axial deformation based on the contribution rate of 2; the whole structure of bending shear deformation than the s coefficient; 3 truss stiffness coefficient E_f based on the 4 reduction; material efficiency index of the component stress based on MEI_c; 5 based on structural efficiency factor structure layout. Comparison of the scope of application, the coefficient optimization criterion, hierarchical optimization, advantages and disadvantages, and make the prospect of it is worthy of further study. The structure efficiency coefficient can promote the improvement and innovation of structure the system can be used in engineering design, to provide effective guidance for structure optimization design.
