Under the Dome, Defining New Landmarks in East Africa: Empowering Public Spaces with Our Bespoke Design

图片
  On the skylines of Nairobi, Addis Ababa, and Dar es Salaam, modern municipal buildings are rising. With East Africa’s economic growth and the preparation for major international events and cultural festivals, stadiums, museums, and convention centers are no longer just functional structures – they have become the “calling cards” that showcase a city’s ambition and vitality.   However, when developing such large-scale public buildings, owners and government bodies often face a key challenge: how to achieve unobstructed, large-span spaces while balancing aesthetics and safety? Traditional concrete structures struggle to meet the open-view requirements of stadiums or the artistic fluidity of museums. That is exactly where our expertise comes in. As a team specialized in steel structure design with multiple successfully delivered municipal projects in East Africa, we deeply understand the social significance of these buildings. We provide not just steel structures, but fully tai...

What are the options for building a mosque for 5,000 people in Saudi Arabia?

 

I. Design codes and loading requirements

💖1. Saudi Building Code (SBC 301) Core Parameters

Seismic design: according to Class II site category, seismic acceleration of 0.25g, seismic force calculation using the equivalent lateral force method, the main structure displacement angle limit of 1/200.

Wind load: basic wind pressure is 0.75kN/m² (100-year return period), equivalent wind pressure is 1.2kN/m² after considering height coefficient, local wind suction coefficient is 1.5.

Snow load: reference to the historical data of Mecca area, the additional roof load is calculated as 0.5kN/m².

💖2. Functional space indicators

1.5000 people worship space needs main hall net area 3500m² (calculated at 0.7m²/person).

2.suggests a 45m x 80m rectangular plan, with a central dome 30m in diameter, flanked by wavy vaults.

II. Specialised disaster-resistant design 

    💖1. Wind-resistant design

1. Installation of deflector plate (angle 25°) in the gable to reduce vortex vibration.

        2. Experimentally verified by Xuzhou Sufang Wind Tunnel: the wind pressure                  coefficient is reduced by 37% when the wind angle is 45°.


💖2. Seismic construction

1. Adopt double lateral force-resisting system: central dome as rigid frame + peripheral arch as articulated support

2. Viscous dampers (damping coefficient C=2500kN-s/m) are set up at 1/4 of the span.

III.Recommended technology mix programmes

💖body structure:Single-layer mesh shell + space truss arch on both sides
هيكل الجسم: غلاف شبكي أحادي الطبقة + قوس دعامة فراغي على كلا الجانبين

💖protective structure:Aluminium-magnesium-manganese panels with vertical locking edges + photovoltaic
هيكل واقي: ألواح من الألومنيوم والمغنيسيوم والمنغنيز مع حواف قفل عمودية + خلايا كهروضوئية
