【提要】  框架結(jié)構(gòu)柱網(wǎng)尺寸的選擇不僅需要符合建筑設(shè)計(jì)和使用的要求，同時(shí)還要保證經(jīng)濟(jì)合理、施工方便。定性和定量分析了影響柱網(wǎng)尺寸確定的主要因素：工程造價(jià)、耗材量、施工技術(shù)難度、施工工期、空間使用率等，得出了它們與柱網(wǎng)尺寸的關(guān)系：柱距的增大使耗材量增大，但并不一定提高工程造價(jià)，造價(jià)與柱距基本成二次曲線增長，并存在一個(gè)合理的造價(jià)最低點(diǎn)。利用模糊綜合評定理論，建立了選擇柱網(wǎng)尺寸的評定模型。通過工程實(shí)例，找出了最經(jīng)濟(jì)合理的柱網(wǎng)尺寸，并證明模糊綜合評定法對具有多因素干擾的評定具有簡明適用的特點(diǎn)。

Economic Analysis and Optimum Choice for Arrangement of Columns in Frame Structure/Li Jianfeng,Zhang Ying,Xiong Qingyuan,Luo Jianguo(School of Construction Engineering,Chang'an University,Xi'an 710061,China)
Abstract:In the frame structure,the choice of arrangement for coloumns should not only accord with the architecture design and the requirement of using,but also should insure that it is economical and convenience for construct.Aiming at the main factors with influence the confirm of the arrange for columns,such as the cost of the construction, the consumption of the material, the degree of the difficulty for construction, time,the rate of using the room,qualitative and quantitative analysis is made;according to the date from the specific project, relationship between the main factors and the change of the distance of columns is concluded.The increasing of the distance for coloumns brings the increasing of consumption, but not for the cost,and there will be a lowest point for the cost.The results improve that the fuzzy comprehensive appraisal method is a simpleunderstand and applicable method when it is used in  evaluation which is influnced by several factors.
Keywords:structure engineering;influence factors;integrative beneficial;fuzzy comprehensive appraisal method
