Structural and Seismic Design and Construction

Afghanistan is located in a high seismic region. Our structural engineers consider the hazards of earthquake with latest international codes such as ASCE. Site visit plays an important role in determining the type of structure designed. Resistance of soil must be determined prior to any kind of activity. Then the interaction of soil and structure must be simulated considering permissible assumptions. Then with regard to type of applicability of occupancy category must be determined based on ASCE code. Importance factor which is only a function of occupancy factor then will be adopted. One the most important role of importance factor is in calculating seismic lateral forces exerted on the structure. But before any calculation, seismic design category (SDC) should be specified.  SDC depends on occupancy category and design level spectral accelerations. Spectral accelerations, in turn, depends of site class and type of soil on the site. With these parameters, the effect of lateral earthquake force can be simulated on the structure. Depending on the period of the structure and its height, type of structure can be adopted which might be concrete, steel, or even wooden structure.

With respect to cultural, technical, and economical factors, the majority of buildings designed in Afghanistan are constructed of reinforced concrete. In order to satisfy safety requirements, ACI318 for designing of high resistance reinforced concrete structure will be adopted. Detailing will be drawn with pinpoint accuracy.

Even with the best design, a structure will fail to function in intense earthquakes, if it is not built with accuracy and honesty. We can assure you of our honesty with adopting newest methods of management. PMBOK standards is one the most widely used guideline in project management in the world. We use the standard to make well aware of costs of project and reasons why your project is delayed. However, we feel obliged to provide with feasibility study prior to the start of project. Therefore, economic, social factors will be appraised to make sure whether your project is profitable or not.
