In order to explore the “strong column weak beam” seismic design principles of reinforced concrete frames, two lattice system columns with V-braces and X-braces and a test specimen without brace were designed for cyclic tests. Based on the test results, the cracking load, ultimate bearing capacity and failure modes were obtained. Hysteretic curves, skeleton curves, deformation and ductility coefficient ability of seismic performance of the latticed system columns with RC braces were analyzed and compared with the specimens without braces. Experimental results indicate that good seismic performance can be obtained for the Latticed System Columns with RC braces, and its resistant lateral stiffness increases obviously. For lattice system columns with RC braces the plastic hinges of braces and beams unusually appears in advance, which makes the structure easy to realize the target of seismic design of “strong column weak beam”，however, the lattice system columns without the RC braces do not show such trend.
為探索實(shí)現(xiàn)鋼筋混凝土框架中的“強(qiáng)柱弱梁”的抗震設(shè)計(jì)原則，該文設(shè)計(jì)兩個(gè) 支撐形式分別為人字形、交叉形的格構(gòu)化體系柱和一個(gè)無(wú)支撐的格構(gòu)化體系柱試件，并 對(duì)其進(jìn)行低周期反復(fù)荷載試驗(yàn)。得出格構(gòu)化體系柱的開(kāi)裂荷載、極限承載力和破壞形態(tài)， 分析帶RC支撐的格構(gòu)化體系柱的滯回曲線、骨架曲線、變形能力、延性等抗震性能， 并和無(wú)支撐的格構(gòu)化體系柱進(jìn)行對(duì)比分析。分析結(jié)果表明：帶RC支撐的格構(gòu)化體系柱 的極限承載力、抗側(cè)剛度等抗震性能較無(wú)支撐格構(gòu)化體系柱有明顯的提高。在帶RC支 撐的格構(gòu)化體系柱中，支撐和梁往往先于柱子出現(xiàn)塑性鉸，使結(jié)構(gòu)容易實(shí)現(xiàn)“強(qiáng)柱弱梁” 的抗震設(shè)計(jì)目標(biāo)，而不帶RC支撐的格構(gòu)化體系柱卻很難實(shí)現(xiàn)。
