爆炸荷载作用下钢板-RPC抗爆门动态响应分析

针对梁板式钢抗爆门空腔降低其抗爆性能的问题,提出了将抗冲击性能良好的活性粉末混凝土(RPC)填充于钢抗爆门空腔,以提高其抗爆能力的方法。基于LS-DYNA有限元平台,对钢板-RPC抗爆门进行动态响应有限元模拟,并与试验数据进行对比,验证了模型的正确性。分析结果表明:钢板-RPC抗爆门抗爆能力明显优于钢抗爆门和钢板-混凝土抗爆门;增加钢板内肋数量、增大门扇钢板厚度能够显著减小抗爆门门扇中心位移;而钢板内肋厚度、RPC强度等级对抗爆门的动态响应影响相对较小。基于分析结果,提出了不同抗爆等级下钢板-RPC抗爆门的设计建议,可供抗爆工程设计选用。     

多扇滑动门锁紧元件与电气装置设置的分析

在一次验收检验中，发现一台间接连接的两扇滑动门没有装有电气安全装置来证实闭合位置的电梯。这台电梯的门扇是采用钢丝绳间接机械连接的，在锁紧门扇与其他门扇之间采用了一个挡块来挡住，以防止间接机械连接失效时其他门扇被打开（如图所示）。那么是否采用了挡块，其他的门扇就不用装设电气安全装置来证实闭合位置呢？

一起人员坠入电梯井道事故的反思

2005年初，福州某酒店内一正常运行中的电梯3楼层门门扇受外力作用，引起下端滑块脱出地坎滑槽，致使一酒后男子从该门扇位置坠落井道死亡。经现场勘察发现，该门扇表面及门扇下端滑块未出现明显变形，滑块脱出地坎滑槽并朝井道内靠在地坎边上，整个门扇仍悬挂在层门导轨上，层门电气机械联锁装置有错位变形。事故发生后特种设备监督检验机构组织人员对该事故进行调查分析，认为3楼该层门是在受到外力的作用下，使门扇发生弹性变形，导致门扇下端滑块脱出层门地坎滑槽。最终使3楼层门失去封闭井道口的作用（防坠落保护功能失效）。

Design of geocell reinforced roads through fragility modeling

Several studies have confirmed the geocell reinforcement system as potential road material. However, there is a wide gap between the number of research studies evaluating the geocell in the laboratory and those dealing with road design methods using the geocell. Due to this gap, the geocell system has not reached its full potential in highways. The present study proposes fragility modeling to design low volume roads by considering the geocell reinforced layer's modulus. A predictive model was developed to estimate the geocell layer's modulus using laboratory and finite element analysis results. The results indicate that geocell reinforcement reduces the stresses on the underlying road layers. The developed fragility approach is then used to examine three road designs for Texas's low volume road involving different geocell reinforced layers. The obtained fragility curves indicate the reliability of each of the three road designs against the traffic load and can thereby assist decision-makers in selecting the optimum design. By designing geocell reinforced roads via fragility modeling, highway officials will be able to integrate any uncertainties in the design inputs and check designs against road performance criteria such as rutting and fatigue cracking, and against decision criteria such as cost, emissions, etc.     

Customer interactive building information modeling for apartment unit design

Although apartment houses are efficient buildings in an urban society, they have a drawback in that the design of a unit is so monotonous that it cannot meet various customer needs. To provide customers with individually tailored unit designs, this study proposes customer interactive building information modeling (CIBIM), a type of parametric unit design method. In CIBIM, a parametric 3D modeling tool has been used to create separate fixed walls and movable walls which were linked to lighting and furniture families. Customer satisfaction with CIBIM was evaluated through a survey comparing an actual model house and a new design. The efficiency was evaluated by comparing a number of drawings using conventional methods and CIBIM. In comparison, the results show that the CIBIM provides various designs which reflected individual desire to change. CIBIM represents a means to meet customer needs as well as a way to reduce labor requirements by designers.     

A discursive grammar for customizing mass housing: the case of Siza's houses at Malagueira

The ultimate goal of the described research is a process for mass customizing housing based on computer-aided design and production systems. The current goal is the development of an interactive system for generating solutions on the Web based on a modeling approach called discursive grammar. A discursive grammar consists of a programming grammar and a designing grammar. The programming grammar generates design briefs based on user data; the designing grammar provides the rules for generating designs in a particular style, and a set of heuristics guides the generation of designs towards a solution that matches the design brief. This paper describes the designing grammar using Siza's houses at Malagueira as a case study.     

Fractal-based algorithmic design of Chinese ice-ray lattices

Chinese ice-ray lattices are perhaps one of the earliest and controlled designs of asymmetric and complex patterns applied as a traditional motif in windows. Such intricate and complex designs developed centuries back have created an evident curiosity to explore its underlying geometric rules. Some scholars used the Shape Grammar as a tool to explain and recreate similar patterns. The previous studies conceive the ice-ray lattice design as the iterative subdivisions of a polygon. However, they missed explaining this geometric quality through the discussion of fractal geometry, which can explain the shapes consuming self-similar or self-affine repetitions of itself at different scales. As a novel approach, this paper analytically focuses on the fractal characters of ice-ray lattice designs and uses fractal geometry as a unique tool for generating different types of ice-ray lattices. The significance of this study is the demonstration of the efficacy of fractal geometry and the simple geometric rule of IFS for analyzing and algorithmically modeling complex lattices and cracked-like patterns.     

Effort and effectiveness considerations in computational design evaluation: a case study

Computational building evaluation tools have the potential to provide an effective means to support informed design decision making. Computational modeling, however, comes with a cost. Thereby, the most important cost factor is not software acquisition, but the time needed for learning and using the software. The extent of required time and effort is believed to be one of the main hindrances toward the pervasive use of computational building performance assessment tools by designers: Currently, modeling applications are mostly used, if at all, in the later stages of design and by specialists, rather than architects. However, few studies have explicitly dealt with the ascertainment and quantification of the actual effort needed to understand, master, and apply computational building evaluation tools. Thus, little factual information is available as to the cost and burden of computational building evaluation and its effectiveness in building design support. In this context, the present paper describes a case study, whose motivation was to estimate the time and effort needed by novice designers to computationally evaluate the performance of building designs. A group of senior architecture students participated in the study, learning and using a software application to assess the energy performance of six project submissions for a school building design competition. The outcome of this study (time investment ranges for various components of the modeling activity) was evaluated and further extrapolated to estimate the effort needed for a more comprehensive computational assessment of the environmental performance of these designs.

Optimization of bathroom ventilation design for an ISO Class 5 clean ward

Ventilation is a main method to control the contaminant dispersion within clean wards. In this paper, we investigated the effects of various ventilation designs of the bathroom in an ISO Class 5 clean ward. Specifically, the contaminant dispersion and particle concentrations corresponding to three different ventilation design schemes were characterized and compared using computational fluid dynamics (CFD) analysis. For each design, we examined airflow and particle concentrations for contaminant sources located at two places (i.e., at the toilet seat and on the floor), respectively. Field test was conducted to compare the measured and simulated air velocities and particle concentrations in a hospital clean ward. The implemented CFD modeling of ventilation effects of various designs in this study has proven to accurately characterize airflow and contaminant control in the ventilated space, and has led to optimizing ventilation for the bathroom in an ISO Class 5 clean ward.
