摘要
树懒把两列连接在一起,被认为是束带,使列不移动。树懒可能是悬在地面上的。所以树懒是两列之间的粘合剂。然而,树懒的现实发生在地面上或一对石头上。因此,sloof将接收建筑物的垂直负载。树懒的设计由于这些条件需要改变。分析使用SAP2000程序进行。土壤和岩石配对被建模为弹簧,采用模态参数参数(ks)。分析结果表明,树懒的地基在地面或岩石对上的下降比树懒悬挂的情况要小。平均下降率是26%当树液垂直于地面或一对岩石以上的岩层时,两根柱子之间的衰减和扭曲的角力就会比树液悬挂的状态小。在吊臂上工作的场力矩是正的,而重心是负的。相反,在树懒上工作的音调是负的,而动感是正的。Sloof connecting two columns has been calculated as a tie beam让他们不动了to keep them moving apart。它被认为是吊在地板上的树懒或没有被抓。因此,它就像两个专栏之间的平局一样被证明是正弦。悬停,在战场上,树懒被固定在地面上,或者石头基础上。防止污水进入大楼的垂直负荷。这种情况需要改变设计的思路。一种分析采用了SAP2000的方法。地面和岩石基础是由分级反应模块化而成的。当地面或石头基金会的树懒比吊树的树懒更小的时候,结果表明了脚的解决办法。不同的是平均水平是26%当树液被压在地上或石头基础上被分解成树液时,两脚之间的不同差异就会更小。被吊在衣架上的那一刻是积极的,而被压碎的那一刻是消极的。在contrary中,缓慢磨损在地面或石头基础上的那一刻是消极的,而缩减的那一刻是积极的。正常的0假的设计好的mso-tstyle-rowband-size: 0;mso-tstyle-colband-size: 0;mso-style-noshow:赛;mso-style-priority: 99;mso-style-parent:”;mso-pad alt:0cm 5.4pt 0cm 5.4pt;mso-para-margin: 0cm;mso-para-margin-bottom: 0001pt;mso-pagination: widow-orphan;font-size: 10 . 0pt;font-family: Calibri, sans-serif;mso-bidi- fontfamily:《时代新浪漫》;
Analisis Pengaruh Sloof terhadap Penurunan Fondasi Telapak dengan Simulasi Numeris
Sloof yang menghubungkan dua kolom selama ini diperhitungkan sebagai balok ikat (tie beam) agar kolom tidak bergeser. Sloof diasumsikan menggantung atau tidak bertumpu di atas tanah. Sehingga sloof murni sebagai pengikat antar dua kolom. Namun, kenyataan di lapangan sloof bertumpu di atas tanah atau di atas pasangan batu. Oleh karena itu sloof akan menerima beban vertikal dari bangunan. Desain sloof perlu diubah karena kondisi ini. Analisis dilakukan dengan menggunakan program SAP2000. Tanah dan pasangan batu dimodelkan sebagai spring dengan input parameter modulus reaksi tanah dasar (ks). Hasil analisis menunjukkan bahwa penurunan fondasi telapak pada kondisi sloof bertumpu di atas tanah atau di atas pasangan batu lebih kecil dibandingkan kondisi sloof menggantung. Selisih penurunan rata-rata sekitar 26%. Beda penurunan dan angular distortion antara dua kolom menjadi lebih kecil ketika sloof bertumpu di atas tanah atau di atas pasangan batu dibandingkan kondisi sloof menggantung. Momen lapangan yang bekerja pada sloof menggantung adalah positif sedangkan momen tumpuan adalah negatif. Sebaliknya, momen lapangan yang bekerja pada sloof bertumpu di atas tanah maupun di atas pasangan batu adalah negatif, sedangkan momen tumpuan adalah positif. Sloof connecting two columns has been calculated as a tie beam to keep them from moving apart. It was assumed as the hanging sloof or not rested on the ground. Hence it was purely as a tie between two columns. However, in the field, sloof is rested on the ground or the stone foundation. Therefore the sloof will receive the vertical load of the building. The sloof design need to be changed due to this condition. An analysis was conducted using SAP2000. The ground and the stone foundation were modeled as springs at which the modulus subgrade reaction (ks) was the input parameters. The results showed that the settlement of footing when the sloof resting on the ground or the stone foundation was smaller than the hanging sloof. The difference of the settlement was about 26% on average. Differential settlement and angular distortion between two column footings became smaller when the sloof was rested on the ground or the stone foundation compared to the hanging sloof. The field bending moment that occurred on the hanging sloof was positive, while the restraint moment was negative. In contrary, the field bending moment that occurred on the sloof rested on the ground or the stone foundation was negative, while the restraint moment was positive.
