懸索結(jié)構(gòu)概述

懸索結(jié)構(gòu)

Cable-suspendedstructures

索的形狀是不穩(wěn)定的(隨荷載分布形式變化)。必須采取不同的構(gòu)造措施，以形成各種具有形狀穩(wěn)定性的懸索體系。Theshapeofasinglecableisunstable(variedwithdifferentloaddistributions).Structuralmeasureshavetobetakentoformdifferenttypesofcablestructureswithnecessaryshape-stability.

HybridSystems1.單層索系加重屋面

設(shè)置重屋面的作用——使均布重力荷載具有優(yōu)勢(shì)，以保證初始形狀的相對(duì)穩(wěn)定性。
