格构式构件：一般由两个或多个分肢用缀件联系组成。采用较多的是两分肢格构式构件。Latticestructurecomponent:generallycomposedoftwoormoreconnectingpartsfordividinglimbs.Themostcommonlyusedcomponentisatwoleglatticestructure

缀条和缀板一般设置在分肢翼缘两侧平面内，Thebattenstripandbattenplatearegenerallysetintheplanesonbothsidesofthelimbflange,其作用是将各分肢连成整体，Itsfunctionistoconnecteachlimbintoawhole,使其共同受力，Makethembeartheforcetogether,并承受绕虚轴弯曲时产生的剪力。Andbeartheshearforcegeneratedwhenbendingaroundtheimaginaryaxis.
