Building information modelling promises model-based collaboration between stakeholders in the project design stage. However, data exchange between physical and analytical building models used for architectural design and structural analysis respectively rarely takes place due to numerous differences in building element representation, especially the representation of geometry. This paper presents the realization of a novel data exchange framework between architectural design and structural analysis building models, based on open interpretations on central storage. The exchange is achieved with a new system architecture, where the program redDim was developed to perform the interpretations, including the most challenging transformations of geometry. We deliver a proof of concept for the novel framework with a prototype building model and verify it on two further building models. Results show that structural-analysis models can be correctly automatically created by reducing dimensionality and reconnecting building elements. The proposed data exchange provides a base for missing standardization of interpretations, which facilitates the non-proprietary automated conversion between physical and analytical models. This research fills the gap in the existing model-based communication that could lead to a seamless data exchange.

The heterogeneity of the architecture, engineering and construction (AEC) industry reflects on digital building models, which differ across domains and planning phases. Data exchange between architectural design and structural analysis models poses a particular challenge because of dramatically different representations of building elements. Existing software tools and standards have not been able to deal with these differences. The research on inter-domain building information modelling (BIM) frameworks does not consider the geometry interpretations for data exchange. Analysis of geometry interpretations is mostly project-specific and is seldom reflected in general data exchange frameworks. By defining a data exchange framework that engages with varying requirements and representations of architectural design and structural analysis in terms of geometry, which is open to other domains, we aim to close the identified gap. Existing classification systems in software tools and standards were reviewed in order to understand architectural design and structural analysis representations and to identify the relationships between them. Following the analysis, a novel data management framework based on classification, interpretation and automation was proposed, implemented and tested. Classification is a model specification including domain-specific terms and relationships between them. Interpretations consist of inter-domain procedures necessary to generate domain-specific models from a provided model. Automation represents the connection between open domain-specific models and proprietary models in software tools. Practical implementation with a test case demonstrated a possible realization of the proposed framework. The innovative contribution of the research is a novel framework based on the system of open domain-specific classifications and procedures for the inter-domain interpretation, which can prepare domain-specific models on central storage. The main benefit is a centrally prepared domain-specific model, relieving software developers from so-far-unsuccessful implementation of complex inter-domain interpretations in each software tool, and providing end users with control over the data exchange. Although the framework is based on the exchange between architectural design and structural analysis, the proposed central data management framework can be used for other exchange processes involving different model representations.

AbstrakKaidah struktur seringkali merupakan penghambat proses kreativitas arsitek dalam merancang bentuk bangunan. Banyak karya arsitektur yang hanya bermain pada kemasan saja, tanpa mempertimbangkan efisiensi struktur terutama pada rancangan gedung besar, baik gedung tinggi, maupun bentang lebar. Umumnya gedung tinggi walaupun fungsi dan tampilannya berbeda menggunakan struktur yang sama, yaitu struktur inti dan rangka (core and frames), yang dibedakan dari bentuk (aditif, substraktif, rotasi, repetisi), warna, jenis material, sehingga ketidakteraturan struktur disembunyikan demi mengejar bentuk bangunannya. Hal ini dikarenakan transformasi bentuk sebagai langkah eksplorasi arsitek dalam mewujudkan desainnya tidak menyertakan pertimbangan estetika struktur sebagai bagian dari proses kreatifnya. Pendekatan struktur masih terkesan penuh dengan rumus dan angka yang dianggap akan menghambat proses kreatif dalam olahan bentuk dan ruang. Oleh karenanya tidak sedikit rancangan yang memanipulasi bentuk luarnya dengan konstruksi tambahan, yang cenderung ornamental. Arsitek umumnya menghindar menampilkan struktur sebagai bagian dari estetika,  padahal analisis struktur merupakan proses yang harus dilalui dalam konsep perancangan demi terbangunnya sebuah rancangan gedung. Kajian ini adalah suatu model pendekatan struktur pada gedung tinggi dengan mengikuti tahapan dasar dalam proses analisis struktur. Diharapkan kajian ini dapat memberikan gambaran pendekatan kualitatif pada konsep struktur dan diterapkan dalam proses penyusunan konsep perancangan arsitektur sehingga dapat menghasilkan bentuk struktur yang baik.kata kunci: kaidah struktur, bangunan tinggi, kreativitas arsitek, estetika strukturAbstractRule of structure often is an inhibitor of the process of creativity of architects in designing building’s shape. Many architectural works only play on the packaging, without considering the efficiency of the structure, especially in the design of large buildings, both tall and wide-spanning buildings. Generally, tall buildings although their function and appearance are different use the same structure, namely the core and frame structure, which is distinguished from shape (additive, subtractive, rotation, repetition), color, type of material, so that structural irregularities are hidden in pursuit the building shape. This is because the transformation of form as exploration step in realizing the design architect does not include aesthetic considerations structures as part of the creative process. The structural approach still seems full of formulas and numbers which are considered to hinder the creative process in processing forms and spaces. Therefore many designs manipulate the outer shape with additional construction, which tends to be ornamental. Architects generally avoid presenting structures as part of aesthetics, whereas structural analysis is a process that must be passed in the design concept in order to construct a building design. This study is a structural approach model in tall buildings by following the basic step in the structural analysis process. It is hoped that this study can provide an overview of qualitative approach in structural concepts and could be applied in the process of architectural design concepts so that it could produce the right structural design.key words: rules of structure, tall building, architect creativity, aesthetic structures

Building information modelling (BIM) is an integrated informational process and plays a key role in enabling efficient planning and control of a project in the architecture, engineering, and construction (AEC) domain. Industry foundation classes- (IFC-) based BIM allows building information to be interoperable among different BIM applications. Different stakeholders take different responsibilities in a project and therefore keep different types of information to meet project requirements. In this paper, the authors proposed and adopted a six-step methodology to support BIM interoperability between architectural design and structural analysis at both AEC project level and information level, in which (1) the intrinsic and extrinsic information transferred between architectural models and structural models was analyzed and demonstrated by a business process model and notation (BPMN) model that the authors developed; (2) the proposed technical routes with different combinations and their applications to different project delivery methods provided new instruments to stakeholders in industry for efficient and accurate decision making; (3) a new material-centered invariant signature with portability can improve information exchange between different data formats and models to support interoperable BIM applications; and (4) a newly developed formal material information representation and checking method was tested on a case study where its efficiency was demonstrated to outperform (i) proprietary representations and information checking method based on a manual operation, and (ii) the model view definition (MVD)-based information checking method. The proposed invariant signature-based material information representation and checking method brings a better efficiency for information transfer between architectural design and structural analysis, which can have significant positive effects on a project delivery due to the frequent and iterative update of a project design. This improves the information transfer and coordination between architects and structural engineers and therefore the efficiency of the whole project. The proposed method can be extended and applied to other application phases and functions such as cost estimation, scheduling, and energy analysis.
