榆林學(xué)院17#公寓樓設(shè)計






摘要

該建筑物是榆林學(xué)院17#公寓樓。根據(jù)提供的地形圖和及功能要求的規(guī)定，進行建筑設(shè)計。它的占地面積約835㎡，建筑面積約5007 ㎡。建筑物最高高度為21m。

此建筑物采用鋼筋混凝土框架結(jié)構(gòu)，結(jié)構(gòu)設(shè)計是六度設(shè)防，設(shè)計地震是第一組，場地為Ⅱ類，粗糙度為B類。其設(shè)計內(nèi)容包括結(jié)構(gòu)布置、構(gòu)件估算、內(nèi)力分析、構(gòu)件截面設(shè)計和基礎(chǔ)設(shè)計幾部分。采用整體現(xiàn)澆式，建筑整體剛度較好并進行了進行了地震作用、風(fēng)荷載和豎向荷載的內(nèi)力分析，采用了多種荷載組合方式。

鋼筋混凝土是一種延性材料，為了充分利用這種材料的特性，根據(jù)建筑三級抗震的要求，進行梁端彎矩調(diào)幅，柱端彎矩調(diào)整，剪力調(diào)整等計算，同時注意節(jié)點的設(shè)計，使得建筑的設(shè)計達(dá)到強柱弱梁，強剪弱彎的要求，增加建筑的延性，以提高建筑的使用性能。

在此次設(shè)計中，多層框架結(jié)構(gòu)分析是采用底部剪力法進行地震荷載下的內(nèi)力分析；采用彎矩二次分配法進行豎向荷載的內(nèi)力分析，整個結(jié)構(gòu)的設(shè)計均依據(jù)規(guī)范來計算。

Abstract

This building is located Yulin a multilayered frame student apartment of 17#. According to topographic diagram which provides and function request stipulation, carries on the architectural design. Its area approximately 835m2, floor space approximately 5,007 m2. Building high is 21m。

This building uses the reinforced concrete portal frame construction, the structural design is six garrisons, the design earthquake is the first group, the location is II kind, roughness is B kind. Its design content including the structural arrangement, the component estimate, the plane unit choice, the endogenic force analysis, the component section design and the foundation designs several parts. Used placement ,the construction overall rigidity is better and carries on has carried on the earthquake load, the wind load and the vertical load endogenic force analysis, has selected the many kinds of loads combination method。

The reinforced concrete is one kind of ductility material, in order to fully uses this kind of material the characteristic, according to the building three levels of earthquake resistances requests, carries on the Liang end moment amplitude modulation, the column end moment adjustment, computation and so on shearing force adjustment, simultaneously pays attention to the pitch point the design, causes the building the design to achieve strong column weak Liang, strongly cuts the weak curved request, the increase construction ductility, enhances the construction the operational performance。

   In this design, the multilayer portal frame construction analysis is uses the base shearing force law to carry on under the earthquake load the endogenic force analysis; Uses  base shearing force law to carry on the vertical load the endogenic force analysis, the entire structure design calculates based on the standard。

Key words: Frame; Load; Earthquake resistances; Reinforced concrete
