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

An appropriate choice of building shape and architectural modifications can result in the reduction of motion by altering the flow pattern around a building. Tapering which is one of aerodynamic devices has been known to be effective to reduce acrosswind response [1, 2]. The exterior wind loading patterns on claddings are sensitive to the building shape. When a building has a tapered cross section along the height, the influence of the exterior wind loading patterns on the wind-induced high-cycle fatigue damage of the cladding fastener of the tapered building needs to be found. In this study, the fatigue damage of the cladding fastener of a non-tapered building and two tapered buildings is estimated by using the rainflow cycle counting method and Miner’s rule. The fatigue damage is compared with one another in order to investigate the influence of the tapered cross section on the fatigue damage of cladding fasteners on side faces of tall buildings


The overall response of a building to wind is governed by steady and unsteady aerodynamic characteristics in winds from different directions, and its mechanical properties such as mass, stiffness, and damping. The general characteristics of the response of bluff building shapes are presented. Typical responses for six tall buildings, as well as their dependence on density and damping, are discussed. Statistical predictions of extreme responses required in design decision are determined through the integration of meteorological factors with aerodynamic and structural properties. It is shown how building shape and structural properties can affect the overall predicted performance.
