一旦試驗(yàn)部分被選 擇那么每一相設(shè)計(jì)都是一種分析。 在結(jié)構(gòu)體系中,試驗(yàn)部分已經(jīng)被選為各個(gè)關(guān)鍵部分。F 的情況下水泥發(fā)生水化現(xiàn)象,我們需要保持這個(gè)狀態(tài)方便化學(xué)水化反應(yīng)的發(fā)生,如果干燥過快,會(huì)導(dǎo)致地面開裂。對于墻,梁,柱來說表面的清洗應(yīng)該非常靈活,在加固前應(yīng)該及時(shí)清除鐵銹和其他有害物質(zhì)。 正是因?yàn)檫@種偏差的存在,為了增強(qiáng)混凝土的抗壓承載能力,我們根據(jù)實(shí)際需要對不同標(biāo)準(zhǔn)的木材或形鋼的基本原理進(jìn)行了結(jié)構(gòu)設(shè)計(jì),這兩個(gè)鋼筋混凝土異形截面構(gòu)件受力情況是最合理的。F. It is necessary to maintain such a condition in order that the chemical hydration reaction can take place. If drying is too rapid, surface cracking takes place. This would result in reduction of concrete strength due to cracking as well as the failure to attain full chemical hydration. It is clear that a large number of parameters have to be dealt with in proportioning a reinforced concrete element, such as geometrical width, depth, area of reinforcement, steel strain, concrete strain, steel stress, and so on. Consequently, trial and adjustment is necessary in the choice of concrete sections, with assumptions based on conditions at site, availability of the constituent materials, particular demands of the owners, architectural and headroom requirements, the applicable codes, and environmental reinfo
