الملخص

The geographical location of Palestine along the Aqaba-Dead Sea Transform Fault, the highest seismic active boundary in the Middle East, had put the country in a major hazard over the past history. Although seismic hazards across the area with relatively low probability, the less attention given towards seismic guidelines in both design and construction in the local practice is expected to play a significant role on the intensities of the coming ground shakings.Ribbed slab systems supported on embedded beams and overloaded by superimposed dead loads (SDLs) are a common flooring system in the local construction industry. Literatures focus on the seismic response behavior of ribbed slabs, hidden beams, or heavy constructions indicate an earthquake-prone buildings. Hence, the existing of such undesirable factors combined exceedingly exacerbates the strength of earthquake shaking.In this respect, the factor of SDL which is one reason of heavy construction is studied. Solid slab with drop beams construction is utilized as a flooring system in a set of reinforced concrete framed structures. The framed structures are supposed to be built on three different soil profile types in Nablus, and one more sensitive soil profile type in Jericho. At every particular site, there are three structures sustaining a SDLs of 1kN/m2, 3kN/m2, and 5kN/m2. This, however, is to investigate the impact of the reduction in the SDL at different site effects on the materials cost (Concrete, and steel) of frame beams and columns.The representative computational models are constructed, analyzed and designed using the finite element program SAP2000, Version 19.1.1. The analysis is done by means of modal response spectrum method described in the Minimum Design Loads for Buildings and Other Structure (ASCE/SEI 7-10), whereas the design is accomplished on the basis of the Building Code Requirements for Structural Concrete and Commentary (ACI 318-14).In final conclusion, the developed approach of reducing SDL form 5kN/m2 to 1kN/m2 can reduce the materials cost in the skeletal elements of about 25%.
