【摘要】：在建筑領(lǐng)域中,經(jīng)常需要搭建分割建筑物內(nèi)部空間的墻,以滿足用戶對(duì)不同戶型的使用需求。這類不承重的內(nèi)墻被稱作隔墻。傳統(tǒng)的隔墻普遍具有一些缺陷,如：磚砌隔墻施工繁瑣、耗費(fèi)大量的人力；石膏板玻璃磚類隔墻強(qiáng)度較低、易破壞；大部分隔墻在地震作用下破壞倒塌,容易對(duì)周圍人民群眾的生命財(cái)產(chǎn)安全造成威脅；大部分隔墻破壞后無(wú)法進(jìn)行修復(fù)等等。本文針對(duì)傳統(tǒng)的室內(nèi)隔墻存在的一些缺陷,提出了一種自適應(yīng)抗震隔墻的思路,并就該思路的可行性進(jìn)行了理論分析和試驗(yàn)研究。本文首先介紹了建筑隔墻的發(fā)展?fàn)顩r,分析了常用隔墻的優(yōu)缺點(diǎn),然后針對(duì)現(xiàn)存的一些隔墻缺點(diǎn),并參考抗震設(shè)計(jì)中的三水準(zhǔn)設(shè)防標(biāo)準(zhǔn),提出了自適應(yīng)抗震隔墻的思路,即：在小震作用下,隔墻能夠提高整體結(jié)構(gòu)的剛度；而在中大震作用下,隔墻可以耗散地震輸入到結(jié)構(gòu)中的能量,減少建筑物受到的損傷。同時(shí),在地震作用結(jié)束后,隔墻的主體部分不被損壞,只需更換剛度元件和耗能元件即可對(duì)隔墻進(jìn)行修復(fù)。依照這個(gè)思路,本文提出了新的隔墻構(gòu)造方案：上下墻體采用鋼筋混凝土構(gòu)架,中間使用剛度元件和耗能元件將上下墻體連接成一個(gè)整體隔墻。該方案的理論分析采用了結(jié)構(gòu)力學(xué)求解器,建立結(jié)構(gòu)模型,對(duì)關(guān)鍵部位的受力進(jìn)行分析。試驗(yàn)研究則按照構(gòu)造方案制作了隔墻模型,并使用MTS液壓伺服作動(dòng)器模擬地震作用下的層間位移加載到隔墻模型上。經(jīng)過(guò)多次反復(fù)試驗(yàn),驗(yàn)證了該自適應(yīng)抗震隔墻的可行性,并研究了剛度元件數(shù)量對(duì)隔墻剛度的影響以及耗能元件數(shù)量對(duì)隔墻耗能能力的影響。
[Abstract]:In the field of construction, it is often necessary to build a wall that divides the interior space of the building to meet the user's demand for different types of units. The non load-bearing inner walls are called partition walls. The traditional partition wall generally has some defects, such as the complicated construction of the brick wall, a large amount of human power, the low strength of plasterboard glass brick partition wall and easy breaking. Bad; most walls destroy and collapse under the action of earthquake, it is easy to threaten the safety of life and property of the people around them. Most of the walls can not be repaired after the destruction. In this paper, in view of some defects existing in the traditional indoor partition wall, an adaptive anti-seismic wall is put forward, and the feasibility of this idea is carried out. This paper first introduces the development of the building partition, analyzes the advantages and disadvantages of the common partition wall, and then, in view of the shortcomings of some existing partition walls, and referring to the three standards in the seismic design, proposes the idea of adaptive aseismic partition, that is, the partition wall can improve the overall structure under the action of small earthquakes. Under the action of medium and large earthquakes, the partition wall can dissipate the energy input into the structure and reduce the damage to the building. At the same time, the main part of the wall is not damaged after the end of the earthquake action. The partition wall can be repaired only by replacing the stiffness element and energy dissipation element. In this way, a new partition is put forward in this paper. The structure scheme: the upper and lower walls are reinforced concrete frame, and the upper and lower walls are connected to a whole partition with stiffness element and energy dissipation element in the middle. The theoretical analysis of the scheme adopts structural mechanics solver, establishes a structural model, analyses the force of the key parts, and makes the partition model according to the structural scheme. The MTS hydraulic servo actuator is used to simulate the interlayer displacement under seismic action to the partition wall model. After repeated tests, the feasibility of the adaptive aseismic wall is verified, and the influence of the number of stiffness elements on the stiffness of the partition wall and the influence of the number of energy dissipation elements on the energy dissipation capacity of the partition wall are studied.
