Here are the detailed steps:<\/p>\n\n- \n
<\/span>Geologic Site Analysis<\/strong><\/span><\/h3>\n\n- \n
Studying the soil to determine its properties (such as hardness and bearing capacity).<\/p>\n<\/li>\n - \n
Seismic risk assessment based on maps of the Kingdom's seismic zones.<\/p>\n<\/li>\n - \n
Determine the expected earthquake force (Peak Ground Acceleration) to design the structure accordingly.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n - \n
<\/span>Choosing a construction system<\/strong><\/span><\/h3>\n\n- \n
Tires that are resistant to torque<\/strong>: Provides high flexibility and is suitable for high-rise buildings.<\/p>\n<\/li>\n- \n
Shear walls<\/strong>: Used in mid-rise buildings to distribute lateral loads.<\/p>\n<\/li>\n- \n
Mixed system<\/strong>: Combines tires and walls to strike a balance between flexibility and rigidity.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n- \n
<\/span>Post-tensioned concrete consolidation<\/strong><\/span><\/h3>\n\n- \n
Designing slabs and columns using Post-tensioned concrete<\/strong> To enhance flexibility.<\/p>\n<\/li>\n- \n
Locating and tensioning cables based on engineering calculations.<\/p>\n<\/li>\n - \n
Using advanced design programs such as ETABS or SAP2000 to simulate seismic performance.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n - \n
<\/span>Design by code<\/strong><\/span><\/h3>\n\n- \n
Adhere to the Saudi Building Code (SBC 301), which specifies seismic design requirements.<\/p>\n<\/li>\n - \n
Refer to international codes such as ASCE 7 or Eurocode 8 to ensure compliance with global standards.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n - \n
<\/span>Supervision and implementation<\/strong><\/span><\/h3>\n\n- \n
Collaborate with specialized contractors in Riyadh or elsewhere in the Kingdom to execute the design accurately.<\/p>\n<\/li>\n - \n
Conduct field inspections of the quality of concrete and cables before and after pouring.<\/p>\n<\/li>\n - \n
Ensure timely cable tensioning using precision hydraulic equipment.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n Applied example<\/strong>: In an office tower project in the center of Makkah, HIMMCO utilized a hybrid structural system supported by \u00a0Post Tension<\/strong>allowing the design of floor slabs with open spaces and high earthquake resistance, while reducing costs by 15% compared to traditional concrete.<\/p>\n |
