The meeting of three major tectonic plates makes Indonesia prone to earthquakes, be it the Indo-Australian plate, the Eurasian plate, and the Pacific plate. Earthquakes are caused by the release of energy generated by the pressure caused by moving plates. Its essence is not earthquake that damage building but anticipation of building which must be in earthquake resistant design. In this case, the building structure must be designed to be earthquake resistant. One of earthquake resistant building technology is technology with base isolator system. This study aims to determine the displacement analysis that occurs due to the effects of earthquake on the structure of the building. Both in the use of base isolator and without using base isolator. The design of this structure is done by analyzing the time dynamic history load in the SRPMK building (struktur rangka pemikul momen khusus). With 10 storey floor building, regular shape, in SRPMK building. The structural elements reviewed in analyzing the displacement of the building structure are in a column, either for fixed base building of SRPMK or for SRPMK building with base isolator. Data analysis is done by using SAP2000 computer software. The result of analysis shows that the maximum fixed column SRPMK structure building structure on the 3rd floor reaches 27.97 mm from the base of the SRPMK fixed base. While at the base of the isolator there is a displacement of 5.79 mm from the base of SRPMK base isolator. The result of analysis shows that the building of SRPMK base isolator compared with SRPMK building, the value of displacement of final floor level structure (floor 10) can be reduced to 15.85%. Application of base isolator in this case can be used as its function can reduce earthquake load.Keyword : base isolator, displacement, SRPMK; analysis of time history.
印度-澳大利亚板块、欧亚板块和太平洋板块这三大板块的交汇,使得印尼容易发生地震。地震是由板块运动产生的压力所产生的能量释放引起的。它的本质不是地震对建筑物的破坏,而是对建筑物进行抗震设计的预期。在这种情况下,建筑结构必须设计成抗震的。抗震建筑技术之一是基础隔震技术。本研究旨在确定由于地震对建筑物结构的影响而发生的位移分析。无论是在使用基极隔离器还是不使用基极隔离器。通过分析SRPMK建筑的时动力历史荷载,对结构进行了设计。有10层楼的建筑,规则的形状,在SRPMK建筑。在分析建筑物结构位移时,无论是固定基础的SRPMK建筑物,还是带基础隔振器的SRPMK建筑物,所审查的结构单元都在一柱内。数据分析采用SAP2000计算机软件进行。分析结果表明,3楼SRPMK结构建筑结构的最大定柱距SRPMK固定底座27.97 mm。而在隔离器的底部,与SRPMK基础隔离器的底部有5.79 mm的位移。分析结果表明,与SRPMK结构相比,SRPMK结构的最终层位结构(10层)的位移值可降低到15.85%。在这种情况下可以采用基础隔震器,因为它的作用可以降低地震荷载。关键词:基隔振器;位移;SRPMK;时间历史分析。

The high-rise building structure is prone to lateral forces, mainly due to the force generated by the earthquake. In calculating the multilevel building structure there are 2 ways, namely with Open Frame and Open Frame combination with shear wall. The shear wall is a wall that acts as a stiffener and is also a core wall for rigging entire buildings designed to withstand shear forces, lateral forces caused by earthquakes. so that the horizontal deformation (deflection) becomes small. The analysis used in this research is spectrum response analysis based on SNI 1726: 2012. This research has 3 model of set back building which will be reviewed, that is the model of set back building with special moment frame system, the model of backyard building with shear wall of each side and model of set back building with shear wall only on one side. All load inputs, stiffness and structural dimensions are the same, which differ only the special moment frame system model and the sliding wall placement used. This building has a height of 39.5 meters (10 floors). Based on this data it shows that the deviation result with the deviation modeling for the model is 0.075 m for the X and 0.064 direction for the Y direction for model 2 0.051 m for the X and 0.050 m directions for the Y direction and for model 3 is 0.074 m for the X and 0.048 for direction Y.Keywords: Set Back, Irregular Building, Drift Story, Shear Shear, Shear Wall, Special Moment Resume Frame.
高层建筑结构容易产生侧向力,主要是由于地震产生的力。在多层建筑结构的计算中,有两种方法,即开放框架和开放框架与剪力墙的组合。剪力墙是一种作为加强筋的墙,也是支撑整个建筑的核心墙,旨在承受地震引起的剪力和侧向力。使水平变形(挠度)变小。本研究使用的分析是基于SNI 1726: 2012的频谱响应分析。本研究有三种后退建筑模型,分别是特殊弯矩框架体系后退建筑模型、两侧各有剪力墙的后院建筑模型和仅一侧有剪力墙的后退建筑模型。所有荷载输入、刚度和结构尺寸都是相同的,不同的只是特殊弯矩框架体系模型和所使用的滑动墙布置。这座建筑高39.5米(10层)。根据该数据可知,模型的偏差建模结果在X方向为0.075 m, Y方向为0.064 m,模型2的X方向为0.051 m, Y方向为0.050 m,模型3的X方向为0.074 m, Y方向为0.048 m。关键词:逆退,不规则建筑,漂移层,剪力墙,特殊力矩恢复框架。

The addition of elements such as pozzolan ingredients to concrete mixtures has been proven can increase the value of concrete compressive strength. This study aims to determine the microstructural effect on the replacement of 10% of Portland cement weight with bagasse ash (sugarcane bagasse). Scanning Electromicroscopphy Microscopphy (SEM / EDX) shows the dominant percentage of bagasse ash is Silica element 53% in addition to other elements such as Carbon (C) and Hydrogen (H). The C-S-H unsure bond pattern on concrete mortar shows a Type III bonding pattern at early ages and bonding patterns I and III on mortars that have reached the age of 28 days. Porosity level decreases with increasing age of concrete mortar. With the reduced porosity will increase the density and increase the compressive strength of concrete mortar. This porosity level is lower than that of concrete mortar without the addition of bagasse ash.Key words: Microstructure, silica, concrete mortar, compressive strength, porosity.
在混凝土混合料中掺入火山灰等成分可以提高混凝土的抗压强度值。本研究旨在确定用甘蔗渣灰(甘蔗甘蔗渣)替代10%硅酸盐水泥重量时的微观结构影响。扫描电镜(SEM / EDX)分析表明,甘蔗渣灰分中硅元素占53%,另外还有碳(C)和氢(H)等元素。混凝土砂浆的C- s -H不确定粘结模式在龄期早期表现为III型粘结模式,龄期达到28 d后表现为I型和III型粘结模式。孔隙率随混凝土砂浆龄期的增加而降低。随着孔隙率的降低,将增加混凝土砂浆的密度和抗压强度。该孔隙率水平低于未添加甘蔗渣灰的混凝土砂浆。关键词:微结构,二氧化硅,混凝土砂浆,抗压强度,孔隙率。

Abstract — Industrial waste products can be considered as renewable resources, one of them is a steel manufacturing, which produced dust waste contain sponge iron, scrap metal and other steel wastes that impacted to environment. This waste material was called Electric Arc Furnace Dust (EAFD). This study investigates the feasibility of using EAFD as a cement replacement compared to silica fume (SF) and fly ash (FA) in terms of Chemical composition, workability, setting time, compressive strength and rapid chloride permeability resistance. The results showed that workability of EAFD is almost similar to control even if percentage of EAFD was increased. It is not refer to FA more workable or SF less workable with increase percentage of replacement. Furthermore, the EAFD significantly affect the setting time, which 3% EAFD replacement bring to prolong final setting time to more than 24 hours, while the setting time of SF and FA did not significant affected along with the increase replacement percentage. In addition, the 3% EAFD is optimum replacement for compressive strength and it is equivalent replacement level to 5% SF and 15% FA. Finally, the EAFD enhance the resistance for rapid chloride permeability more than FA but less than SF.
摘要:工业废弃物可以被认为是可再生资源,其中一种是钢铁制造,其产生的粉尘废弃物含有海绵铁、废金属等对环境有影响的钢铁废弃物。这种废料被称为电弧炉粉尘(EAFD)。本研究从化学成分、和易性、凝结时间、抗压强度和抗氯离子快速渗透性等方面考察了EAFD作为水泥替代品的可行性,并与硅灰(SF)和粉煤灰(FA)进行比较。结果表明,即使增加EAFD的添加量,EAFD的可加工性与对照基本一致。这并不是指随着更换百分比的增加,FA更可行或SF更不可行。此外,EAFD显著影响凝固时间,添加3%的EAFD可使最终凝固时间延长至24小时以上,而随着添加比例的增加,SF和FA对凝固时间的影响不显著。此外,3%的EAFD是抗压强度的最佳替代,相当于5% SF和15% FA的替代水平。最后,EAFD对氯离子快速渗透的抵抗能力比FA强,但比SF弱。

Earthquake resistant building must be designed with a proper plan configuration. Although the regular and symmetrical building plans have been known to have a good behaviour under earthquake loads, but the facts have demonstrated that many asymmetrical plan buildings are built for the architectural reasons. Irregular plan buildings cause mass distribution, stiffness, and strength asymmetries which in turn produce the eccentricity to the centre of mass. In this research, the asymmetrical buildings are simulated under earthquake ground motion containing pulse. The study aims to evaluate the drift and floor rotations that occur in the asymmetrical buildings. The results indicate that the difference in drift of symmetrical and asymmetrical buildings reach 8% to 20%. The rotation occurred on the rigid side (high stiffness side) is smaller than the flexible side (low stiffness side). The difference in eccentricity affects clearly the inelastic floor rotation.Keywords: Eccentricity Stiffness, Pulse Ground Motion, Floor Rotation
抗震建筑必须采用合理的平面结构设计。虽然人们已经知道规则和对称的建筑平面在地震荷载下具有良好的性能,但事实证明,许多不对称的平面建筑是出于建筑原因而建造的。不规则的平面建筑导致质量分布、刚度和强度不对称,这反过来又产生了质量中心的偏心。本文对不对称建筑进行了含脉冲地震动模拟。该研究旨在评估不对称建筑中发生的漂移和地板旋转。结果表明,对称与不对称建筑的漂移差值可达8% ~ 20%。刚性侧(高刚度侧)发生的旋转小于柔性侧(低刚度侧)。偏心距的差异对楼板的非弹性旋转有明显的影响。关键词:偏心刚度,脉冲地震动,楼板旋转
