【正文】 al language is structural elements simplified out refined from the building and other specialized drawings of structural engineer, including foundation, wall, column, roof beam, board, stair, fullpage proof detail picture, etc.. Then e to form the structural systems of the building or structures with these structural elements, including verticality and bearing and resist strength system of level, and then various load that situation produce in a most succinct way from transmission to foundation. The stage of the structural design can be divided into three stages on the whole: 1. Structural scheme stage: According to the importance of the building, providing fortification against earthquakes in the earthquake intensity, the geologic prospect report of the project of the building site, classification and height and storey of the building of the building field are counted to confirm the structural form of architecture, what this project is adopted is frame structure。然后用這些結(jié)構(gòu)元素來(lái)構(gòu)成建筑物或構(gòu)筑物的結(jié)構(gòu)體系，包括豎向和水 平的承重及抗力體系 ，再把各種情況產(chǎn)生的荷載以最簡(jiǎn)潔的方式傳遞至基礎(chǔ)。結(jié)構(gòu)設(shè)計(jì)簡(jiǎn)而言之就是用結(jié)構(gòu)語(yǔ)言來(lái)表達(dá)工程師所要表達(dá)的東西。用途上，商住樓可商可住，而純寫(xiě)字樓只能商用；另外價(jià)格上，商住樓更有優(yōu)勢(shì)，它以比住宅稍高比寫(xiě)字樓更低的價(jià)格優(yōu)勢(shì)獲得中小企業(yè)的青睞。
