Shah Alam Sports Complex Design and Construction of Unistrut Space-frame Roof Structure

The Shah Alam Sports Complex is a $100-million multiuse sports facility in Selangor, Malysia. The main feature of this complex is a 72000-seat multisport stadium. Seating on both sides of the stadium will be covered by a pair of barrel-vaulted acrylic sky roofs. Each roof is structurally supported by a Unistrut Space-Frame which in tum is supported at three of its four edges with a free span of 931 feet (284 m). The frame is cantilevered from the back 226 feet (69 m) over the seats. In this paper, design philosophy to satisfy serviceability and ultimate limit states is discussed. Also discussed is the use of successive design approximations to create limited, but efficient, members data base that satisfies design requirements and does not burden, by its size, inventory control and construction. Effects of welding and galvanizing on cold-formed tubes are reviewed. Final analysis and design procedures of the structure and its supports are introduced, and the construction method is discussed

Smart wearable devices in cardiovascular care: where we are and how to move forward.

Technological innovations reach deeply into our daily lives and an emerging trend supports the use of commercial smart wearable devices to manage health. In the era of remote, decentralized and increasingly personalized patient care, catalysed by the COVID-19 pandemic, the cardiovascular community must familiarize itself with the wearable technologies on the market and their wide range of clinical applications. In this Review, we highlight the basic engineering principles of common wearable sensors and where they can be error-prone. We also examine the role of these devices in the remote screening and diagnosis of common cardiovascular diseases, such as arrhythmias, and in the management of patients with established cardiovascular conditions, for example, heart failure. To date, challenges such as device accuracy, clinical validity, a lack of standardized regulatory policies and concerns for patient privacy are still hindering the widespread adoption of smart wearable technologies in clinical practice. We present several recommendations to navigate these challenges and propose a simple and practical 'ABCD' guide for clinicians, personalized to their specific practice needs, to accelerate the integration of these devices into the clinical workflow for optimal patient care
