【摘要】：建筑工業(yè)化所采用的結(jié)構(gòu)形式一般為裝配式結(jié)構(gòu)和半裝配式結(jié)構(gòu),這兩種形式通常采用工廠預(yù)制的鋼筋混凝土墻板進行現(xiàn)場安裝作為其外墻圍護體系,節(jié)省工期。預(yù)制外掛墻板與主體結(jié)構(gòu)通常采用柔性連接和剛性連接,柔性連接一般采用連接件的方式,可以削弱主體結(jié)構(gòu)與外掛墻板之間的聯(lián)系,減少墻板在地震及其它水平荷載作用下所受外力,避免發(fā)生破壞,但其本身并不能對結(jié)構(gòu)剛度產(chǎn)生過多的影響。剛性連接一般采用疊合梁的形式,通過預(yù)制墻板的預(yù)埋鋼筋與梁整體澆筑,與柔性連接相比增強了主體結(jié)構(gòu)與外掛墻板之間的聯(lián)系,所承擔(dān)的地震力及其它水平荷載也較大,容易在節(jié)點處發(fā)生破壞。因此對于剛性連接而言,其節(jié)點設(shè)計尤為重要,對于節(jié)點鋼筋的計算,布置及構(gòu)造措施,目前國內(nèi)并沒有出臺相關(guān)的規(guī)范或技術(shù)規(guī)程。因此各施工單位以及設(shè)計單位均憑借以往經(jīng)驗進行施工與設(shè)計,造成現(xiàn)有的節(jié)點鋼筋形式多種多樣。采用柔性連接避免墻板破壞的同時也削弱了預(yù)制外掛墻板對于主體結(jié)構(gòu)抵抗側(cè)剛度的貢獻,造成材料性能的浪費。為充分發(fā)揮外掛墻板的抗側(cè)能力,本文結(jié)合減震耗能的思想對預(yù)制外掛墻板的節(jié)點預(yù)埋鋼筋進行了優(yōu)化設(shè)計。 首先通過實驗對節(jié)點的抗震性能進行分析,分析了影響其抗震性能的因素,參考現(xiàn)有的節(jié)點做法,提出了一種合理的節(jié)點預(yù)埋鋼筋形式。并對該形式進行了有限元分析,分析結(jié)果表明：該鋼筋形式具有穩(wěn)定的滯回曲線。在此基礎(chǔ)上,對采用此種形式的一榀框架進行有限元分析,并進行對比分析,分析結(jié)果表明：合理的利用外掛墻板的抗側(cè)能力后,相比采用剛性連接不考慮外掛墻板抗側(cè)能力,結(jié)構(gòu)的地震反應(yīng)有一定程度的衰減。通過合理設(shè)計,適度利用墻板的剛度和強度后,將有助于減輕結(jié)構(gòu)的地震反應(yīng)。
[Abstract]:The structure of the form of building industrialization for general assembly structure and semi assembly type structure, the two kinds of commonly used reinforced concrete wall panel factory pre installed on site as its exterior enclosure system, savesthe prefabricated external wall panels and main structures are usually made of flexible connection and rigid connection and flexible connection with connector the way that can weaken the between the structure and the external wall, reducing the force under the action of seismic wall and other horizontal loads, avoid the occurrence of damage, but it is not about the stiffness of the structure to produce too much influence. The general rigid connection by composite beam form, through the embedded prefabricated wall panel pouring steel bar and beam, and the flexible joint has been enhanced between the main structure and the external wall, the seismic force and other horizontal load is large, easy to Failure node. So for the rigid connection, the node design is particularly important for the calculation of joints of reinforced, layout and construction measures, China has not issued the relevant standards or technical regulations. Therefore the construction unit and design unit with the past experience of design and construction, resulting in a variety of forms of the existing reinforced joints diversity. Adopt flexible connection while avoiding panel failure also weakened the prefabricated external wall panels for the main structure of resistance to lateral stiffness contribution caused by material waste. In order to make full use of external wall lateral resistant ability, combining with the idea of node energy dissipation pre buried steel prefabricated external wall panels are optimized.
The author analyzed the seismic performance experiment for the node, analyzes the influence factors of the seismic performance, the reference node existing practice, put forward a reasonable node pre buried steel form. And the form of the finite element analysis, the results show that the reinforced form a stable hysteretic curve. This on the basis of finite element analysis for the frame of this form, and carries on the contrast analysis, analysis results show that the external wall panels of the lateral resistant ability of reasonable use, without considering the connection of external wall panels of lateral resistance compared with rigid, the seismic response of the structure have a certain degree of attenuation. Through reasonable design, proper use the wall stiffness and strength, will help to reduce the seismic response of the structure.
