Parameterization Design

With development of nonlinear construction theory and digital technology, parameterization construction design has drawn extensive attention in construction industry as a new method of solving complex problems in construction. Parameterization design method has broken through the qualitative and transcendental design methods for design issues in the traditional design process. After getting rid of the form constraint of Euclidean geometry, generation of construction space and form is on the judgment basis of quantized data. Such bottom-up dynamic design process has broken through imprisonment of traditional form and construction design has returned to the original point of rational creation. In this paper, a certain foundation is laid for theoretical researches on development, influence and future of parameterization design from the aspects of parameterization design concept, tool, scheme generation, its influence on design thinking, etc.

Specialist Groups

To begin this investigation, one asks, ‘What is an Engineer’s Design Studio?’ This paper examines the work and statements of three groups in an attempt to answer this question and define their significance. It must be acknowledged that the term ‘Design Studio’ is not a label chosen by all of these firms, but one suggested here to encapsulate their work. An Engineer’s Design Studio is a group of engineers engaging in building design. In fact, they are small specialist groups that seek to contribute to the design by challenging the existing assumptions in the design process. By asking bigger questions about a project than their discipline normally allows, a differing viewpoint emerges. These groups use engineering to articulate architectural visions. Again, not necessarily visions of the architect, for which they consult, but visions for the project that they are supporting. The difference is that engineering can be used in the creation of the ideas behind a project and not just in the articulation of the project. Additionally, the groups seek innovation through the use and growth of digital technology. Design studios within engineering firms in the construction industry are not common. Their existence has much to do with the changes occurring in this digital age. Digital technology not only influences architectural practice, it also reaches into the pedagogy of architectural education. By using the Engineer’s Design Studio as an example, one can see how the engineer’s aims can be applied to the benefit of current architectural education practices.

Implementation Progress

Although applying industrialization methods on the construction industry is well-documented as one of the best solutions of high housing demands, implementation progress of industrialized building system (IBS) rather slow is picking up due to barriers associated with complexity of its design stage. The paper presents an extant literature survey focusing on application of modular design process on IBS projects to benefit from abstraction of design process of these projects in order to facilitate the industrialization process of the construction industry. Results indicate that designing based on modularization could assist design process of IBS projects so that it prevents emerging conflicts in IBS life span that is rooted in IBS design stage. The study is presently expecting to improve awareness in various phases of IBS projects regarding the significance contributions of Modular Design Method as a respond to the complexity of IBS design method.

The article discusses methods for optimizing the design of the Neutron Converter research plant design with parameters that are most suitable for a particular consumer. 38 similar plant structures with different materials and sources were calculated, on the basis of which the most optimal options were found. As part of the interaction between OKBM Afrikantov JSC and the Nizhny Novgorod State Technical University named after R. E. Alekseev, the Neutron Converter research plant was designed and assembled. The universal neutron converter is a device for converting a stream of fast neutrons emitted by isotopic sources into a "standardized" value of flux density with known parameters in the volume of the central part of the product, which is the working part of the universal neutron converter. To supply neutron converters to other customer organizations (universities, research organizations and collective centers), it is necessary to take into account the experience of operating an existing facility, as well as rationalize the design process of each specific instance in accordance with the requirements of the customer.

In order to improve the durability of the asphalt pavement on a cement concrete bridge, this study investigated the effect of the modulus of the asphalt mixture at the bottom layer on the mechanical response of bridge pavement, along with a type of emerging bridge pavement structure. In addition, the design method and pavement performance of a high-modulus asphalt mixture were investigated using laboratory and field tests, and the life expectancy of the deck pavement structure was predicted based on the rutting deformation. The results showed that the application of a high-modulus asphalt mixture as the bottom asphalt layer decreased the stress level of the pavement structure. The new high-modulus asphalt mixture displayed excellent comprehensive performance, i.e., the dynamic stability reached 9632 times/mm and the fatigue life reached 1.65 million cycles. Based on the rutting depth prediction, using high-modulus mixtures for the bridge pavement prolonged the service life from the original 5 years to 10 years, which significantly enhanced the durability of the pavement structure. These research results could be of potential interest for practical applications in the construction industry.

Floor System

Under high gravity loads, steel double-beam floor systems need to be reinforced by beam-end concrete panels to reduce the material quantity since rotational constraints from the concrete panel can decrease the moment demand by inducing a negative moment at the ends of the beams. However, the optimal design process for the material quantity of steel beams requires a time-consuming iterative analysis for the entire floor system while especially keeping in consideration the rotational constraints in composite connections between the concrete panel and steel beams. This study aimed to develop an optimal design method with the LM (Length-Moment) index for the steel double-beam floor system to minimize material quantity without the iterative design process. The LM index is an indicator that can select a minimum cross-section of the steel beams in consideration of the flexural strength by lateral-torsional buckling. To verify the proposed design method, the material quantities between the proposed and code-based design methods were compared at various gravity loads. The proposed design method successfully optimized the material quantity of the steel double-beam floor systems without the iterative analysis by simply choosing the LM index of the steel beams that can minimize objective function while satisfying the safety-related constraint conditions. In particular, under the high gravity loads, the proposed design method was superb at providing a quantity-optimized design option. Thus, the proposed optimal design method can be an alternative for designing the steel double-beam floor system.

The subject of the presented paper is the validation of a design method for HP and IP steam turbine stages. Common design processes have been operating with simplified design methods in order to quickly obtain feasible stage designs. Therefore, inaccuracies due to assumptions in the underlying methods have to be accepted. The focus of this work is to quantify the inaccuracy of a simplified design method compared to 3D Computational Fluid Dynamics (CFD) simulations. Short computing time is very convenient in preliminary design; therefore, common design methods work with a large degree of simplification. The origin of the presented analysis is a mean line design process, dealing with repeating stage conditions. Two features of the preliminary design are the stage efficiency, based on loss correlations, and the mechanical strength, obtained by using the beam theory. Due to these simplifications, only a few input parameters are necessary to define the primal stage geometry and hence, the optimal design can easily be found. In addition, by using an implemented law to take the radial equilibrium into account, the appropriate twist of the blading can be defined. However, in comparison to the real radial distribution of flow angles, this method implies inaccuracies, especially in regions of secondary flow. In these regions, twisted blades, developed by using the simplified radial equilibrium, will be exposed to a three-dimensional flow, which is not considered in the design process. The analyzed design cases show that discrepancies at the hub and shroud section do exist, but have minor effects. Even the shroud section, with its thinner leading-edge, is not vulnerable to these unanticipated flow angles.
