摘要: 加腋梁加腋板樓蓋是基于地下室頂板的大跨度和高承載需求而產(chǎn)生的新型樓蓋形式. 首先詳細介紹該樓蓋結構布置形式和構造,并簡要說明常見加腋梁板計算方法的局限性,提出使用有限元非線性分析方法進行計算;隨后重點分析加腋部分對梁板彎矩分布、配筋及造價的影響,得出在受力特性良好和造價較低的情況下梁和板的最優(yōu)加腋尺寸及加腋梁板配筋的最不利位置;最后通過與單向板主次梁樓蓋對比來深入分析該樓蓋的經(jīng)濟性.結果表明,加腋梁加腋板樓蓋的平均設備成本,在普通荷載和常 6 級人防荷載作用下的平均結構成本、平均綜合成本均較低,因此該樓蓋應在地下室頂板中予以推廣.

Abstract: Based on the need of the large span and high bearing capacity in the top plate of basement, the floor withhaunched beam and haunched slab was produced as a new?type structure. At first, the structural arrangement and details ofthis floor were introduced minutely, and the limitations of common calculation methods for the haunched beam and thehaunched slab were illustrated briefly, then the non?linear finite analysis method for calculation was proposed. Secondly,the influence of the haunched parts on the bending moment distribution, reinforcement, cost in beam and slab wasemphatically analyzed, then the optimum haunched sizes of the beam and slab, and the most unfavorable position ofreinforcement of haunched beam and slab were obtained under the condition of good mechanical characteristics and low cost.At last, the economy of the floor with the haunched beam and the haunched slab was analyzed deeply by comparing with theone?way floor system of main?secondary beams. The results show that the average equipment cost of the floor with haunchedbeam and haunched slab, the average structure cost and the average combined cost of this floor under the action of thenormal load and grade 6 civil air load for conventional weapon were lower. Therefore, it should be popularized in the topplate of basement.
Keywords: floor with haunched beam and haunched slab; the top plate of basement; non?linear finite analysis; theoptimum haunched size; economy
