摘 要

[摘要]對(duì)體內(nèi)張拉成形網(wǎng)格結(jié)構(gòu)的預(yù)應(yīng)力損失進(jìn)行了初步分析,并對(duì)各種預(yù)應(yīng)力損失給出了相應(yīng)的補(bǔ)償措施。通過算例介紹了適用于分批張拉的張力補(bǔ)償法,研究?jī)?nèi)容對(duì)該結(jié)構(gòu)的工程設(shè)計(jì)及施工有一定指導(dǎo)意義。

Analysis and compensation method of prestress losses in internal stretch forming lattice structure
Hou Guohua, Zhang Yigang(Space Structure Research Center, Beijing University of Technology, Beijing 100124, China)
Abstract:Preliminary analysis of prestress losses was presented for internal stretch forming lattice structures, and corresponding compensation measures were given for the prestress losses.And tension compensation law that adapt to the batches stretch was introduced by an example.The results can lead to the engineering design and construction of this structure for the future.
Keywords:internal stretch forming lattice structure; prestress losses; compensation
