沐蓝天碧波 树绿色建筑——访深圳蓝波绿建集团总裁徐宁

我们想让建筑包含更多的东西,流血的、精力耗尽的、让人眩晕的、甚至破碎的;出血的、让人疼痛的、破裂的、有压力的、哭泣的。建筑应该是多孔的、炽热的、光滑的、坚硬的、有棱角的、野蛮的、圆形的、精细的、有色彩的、讨人厌的、贪婪的、做梦般、引诱人的、反叛的、湿的、干的和跳动的。活着或者死的。冷的,就如一块冰一样冷;热的,就如绚烂夺目的翼一样热。建筑必须绚烂夺目。——库珀·希墨尔布劳《建筑必须绚烂夺目》

关于建设工程安全生产管理的探讨

随着我国的各种政策上的改革,我们国家的建筑市场上的封闭性大大的减弱,对外的开放也进一步的加大。因此越来越多的外国的建筑公司对我国的建筑市场的建筑的份额参与进来,所以我们国家的建筑业的竞争加大了很多。但是我们国家的建筑工程在实际施工工过程中的事故频繁发生,而且其中高危险、高发生率大大的减弱我们国家的建筑企业在市场上的竞争能力。而按照我们国家的一些专家的说法,事故产生的经常性发生的根本原因是建设时对其的工程上的管理不够。因此,本文就以工程建设过程中发生事故的原因进行基本的分析,并且对其的管理措施进行适当的探讨。

超高层建筑伸臂桁架“延迟连接”技术在沈阳恒隆广场主塔楼施工中的应用

在水平荷载起控制作用的超高层建筑中,设置伸臂桁架可以提高结构的整体工作性能,从而提高结构的抗侧刚度,控制结构的顶部位移,降低核心筒所承担的倾覆力矩。但是,伸臂桁架在施工阶段,由于内外筒施工不同步,结构布置不对等原因,会导致施工过程中内、外筒的变形存在一定差异,如果盲目施工,将会造成在伸臂桁架内部过早产生较大应力,导致结构成形后整体受力状况与原结构设计模型不符。通过研究,提出一种超高层伸臂桁架"延迟连接"的施工技术。该方法在沈阳恒隆广场主塔楼施工应用的情况表明,可有效解决外框与芯筒不均衡变形导致的伸臂桁架应力过大的问题,确保了伸臂桁架施工和使用阶段的结构性能。     

Progressive collapse resisting capacity of building structures with outrigger trusses

In this paper, the progressive collapse potential of building structures with core and outrigger trusses were evaluated using nonlinear static and dynamic analyses. To this end 36‐storey analysis model structures composed of RC core walls and perimeter frames connected by outrigger trusses at the top were prepared. The static pushdown analysis of the structure with mega‐columns and outrigger trusses showed that the maximum strength reached only about 20% of the load specified in the US General Services Administration guideline when a mega‐column in the first storey was removed. According to dynamic analysis results, the vertical displacement monotonically increased until collapse as a result of buckling of some of outrigger truss members. However the structure with outrigger and belt trusses remained stable after a perimeter column was removed. The stability of the structure with mega‐columns and outrigger trusses could be achieved by redesigning it with additional belt trusses or with moment connections in interior or exterior frames. Based on the analysis results it was concluded that the dynamic amplification factor of 2.0 recommended in the guidelines provided reasonably conservative results.

Determination of optimum location for flexible outrigger systems in tall buildings with constant cross section consisting of framed tube,shear core,belt truss and outrigger system using energy method

In this paper, based on maximizing the outrigger-belt truss system’s strain energy, a methodology for determining the optimum location of a flexible outrigger system is presented. Tall building structures with combined systems of framed tube, shear core, belt truss and outrigger system are modeled using continuum approach. In this approach, the framed tube system is modeled as a cantilevered beam with box cross section. The effect of outrigger and shear core systems on framed tube’s response under lateral loading is modeled by a rotational spring placed at the location of belt truss and outrigger system. Optimum location of this spring is obtained when energy absorbed by the spring is maximized. For this purpose, first derivative of the energy equation with respect to spring location as measured from base of the structure, is set to zero. Optimum location for outrigger and belt truss system is calculated for three types of lateral loadings, i.e. uniformly and triangularly distributed loads along structure’s height, and concentrated load at top of the structure. Accuracy of the proposed method is verified through numerical examples. The results show that the proposed method is reasonably accurate. In addition, for different stiffness of shear core and outrigger system, several figures are presented that can be used to determine the optimum location of belt truss and outrigger system.     

旋转惯容阻尼伸臂控制体系减震性能研究

旋转惯容阻尼器(rotation inertia damper,RID)具有质量小、阻尼力大的特点,应用于伸臂结构体系时必须考虑其转动惯量的影响。通过研究RID工作机理,推导了RID伸臂控制体系的振动微分方程,并提出了该体系的地震响应简化算法;考虑RID转动惯量影响,研究了结构各参数与地震响应的关系及其对减震效果的贡献。结果表明：RID伸臂控制体系的地震响应简化算法计算结果合理,与有限元法结果吻合较好;RID的质量参数对伸臂位置及阻尼参数的最优值影响甚微,而且对结构地震响应的影响也可忽略;外柱刚度将显著影响伸臂位置与阻尼器参数的最优值,而且当外柱刚度较大时有利于RID的性能发挥;RID伸臂控制体系具有良好的减震性能,即使在RID质量参数较大的情况下,也能保证其阻尼力在等效力中起主导作用。     

Optimized use of the outrigger system to stiffen the coupled shear walls in tall buildings

Based on the conventional yet accurate continuum approach, a general analysis is presented for a pair of coupled shear walls, stiffened by an outrigger and a heavy beam in an arbitrary position on the height. Subsequently, a parametric study is presented to investigate the behavior of the structure. The optimum location of the outrigger and the parameters affecting its position were also investigated. The results showed that the behavior of the structure can be significantly influenced by the location of the outrigger. It was also indicated that in most ordinary cases the best location of the structure to minimize top drift is somewhere between 0·4 to 0·6 of the height of the structure. Though this method is not a substitute for the finite element method, it gives an initial simple solution to determine the size and position of outrigger, stiffening beam and coupled shear walls in the preliminary design stages.

Shear wall with outrigger trusses on wall and column foundations

A graphical method of analysis is presented for preliminary design of outrigger truss‐braced high‐rise shear wall structures with non‐fixed foundation conditions subject to horizontal loading. The method requires the calculation of six structural parameters: bending stiffness for the shear wall, bending and racking shear stiffnesses for the outrigger, an overall bending stiffness contribution from the exterior columns, and rotational stiffnesses for the shear wall and column foundations. The method of analysis employs a simple procedure for obtaining the optimum location of the outrigger up the height of the structure and a rapid assessment of the influence of the individual structural elements on the lateral deflections and bending moments of the high‐rise structure. It is concluded that all six stiffnesses should be included in the preliminary analysis of a proposed tall building structure as the optimum location of the outrigger as well as the reductions in horizontal deformations and internal forces in the structure can be significantly influenced by all the structural components.

Strength demand of dual‐purpose outrigger system for reducing lateral displacement and differential axial shortening in a tall building

Certain maximum lateral displacement (LAT) and differential axial shortening (DAS) values can lead to the deterioration of the serviceability of a structure. Previous studies indicated that an outrigger system can be used to control both the DAS and the LAT in a tall building. In order to enhance the applicability of the dual‐purpose outrigger system, the amount of stress developed on the outrigger due to the reductions of the LAT and DAS should be determined. Therefore, in this study, the stresses due to the LAT and DAS were analyzed in terms of the reduction ratio of the LAT and DAS, and the absolute sum of stresses, which was the strength demand of the outrigger, was evaluated as well. To identify the parameters affecting the additional stress of the outrigger, analytic equations were proposed to predict the additional shear force acting on the outrigger due to DAS reduction. A finite‐element analysis was performed to quantitatively identify the reduction ratio of the LAT and DAS as well as the resulting stress by changing four parameters: the stiffness, location, number, and connection time of outriggers. The results demonstrated that the stress of the dual‐purpose outrigger can be minimized by adjusting the design parameters.     

基于B3模型的竖向构件差异变形分析

为研究巨型框架伸臂核心筒结构中由收缩和徐变引起的巨柱和核心筒的竖向差异变形,基于B3收缩徐变模型,采用应变增量法进行MATLAB编程,模拟荷载逐层施加的实际施工过程。对某一巨型框架伸臂核心筒结构进行了研究,考虑施工过程、混凝土收缩和徐变影响,对高层混凝土结构构件在竖向荷载作用下的竖向变形进行了计算;计算构件在楼板施工前后巨柱和核心筒的弹性、非弹性缩短以及竖向差异变形;进行了差异缩短变形分析,采用逐层修正法进行补偿。结果表明：考虑重力荷载、混凝土收缩和徐变时,巨柱和钢筋混凝土筒由收缩和徐变产生的非弹性变形占总变形的509／6以上,且该比例随时问呈增大趋势;巨柱和核心筒的收缩变形远小于徐变变形,收缩和徐变变形最终趋于一定值;楼板施工结束时竖向变形近似相等的构件,在楼板施工后一定时期的竖向差异变形很大;若顸层楼板施工结束时荷载全部施加完毕,则楼板施工后的最大竖向变形值出现在中间某一层;对于有具体要求的特殊结构,采用逐层修正法可降低差异变形在伸臂桁架中引起的附加内力。
