THE EARTHQUAKE RESISTANT CONCRETE FRAME BUILDING – WITH SPECIAL FOCUS ON BEAMS AND COLUMNS In this paper we are going to compare two codes on the basis designing the earthquake resistance concrete frame building. The comparison focuses around beam and columns of the building…

Introduction

Iranian Code 8% Euro code 4% Table 1 For Eurocode the effective flanged width is ‘bff’ and for Iranian code it is ‘b’ Figure 1 Special condition should be followed when the beam elements are being designed such as the difference between rectangular beam and flanged beam should be known. Flanged beams are generally the rectangular beams which work with slabs and the part of slab element acts with the top part of the beam. If it is below the flange, then the section needs to be designed by taking into consideration the specific area of concrete section for compression part. The most crucial part in design is the design for flexure and shear. The flexure design has to be repeated twice, one for support condition and another for span condition. Design of Beam Sections under Iranian Standard: Isolated T-Beam Figure 2 Figure 3 Rectangular beams with tensile reinforcing: For this type the beam width b equals to 12 in (305mm) when the moment and shear are expressed per foot (m) of width. The working stress design formula for this is as follows: b = width of beam [equals 12 in (304.8 mm) for slab], in (mm) d = effective depth of beam, measured from compressive face of beam to centroid of tensile reinforcing M = bending moment, lb . ...

Another incident claimed 1000 people in 1981 in Kerman while 40,000 faced the same in Gilan, a province in Northern Iran. The Ritcher scale reading struck 7.2. An earthquake that occurred in Bam in December 2003 is numbered among the 130 major earthquakes in Iranian history with estimated casualty cases of 30-50 thousand (Iranian Studies Group, 2004, p.2).

Steel building design
At the same time, the design should also ensure and provide the necessary comfort, energy-efficiency and safety to the inhabitants. To attain the fundamental building requirements, it is then necessary to integrate adequate structural resistance to building designs. The primary purpose of this is to sustain the actions (i.e. loads, imposed displacements, thermal strains) and influences resistance…
Seismic Response of Reinforced Concrete Frame Buildings with Different Ductility Classes Using EC8 and EC2
The concept of reinforced concrete was first initiated in Japan during the 1950s. However in the initial times, the use of the RC buildings was not considered as significant, a situation that has modified in the present times (Aoyama, 2001, pp.1-2). Considering natural calamities like the earthquake, it is essential that the constructed buildings are based on such materials that are capable of…

Earthquakes trigger one mode of vibration which is the lowest fundamental mode besides higher modes which take place as a result of tremors. 2.1 Development of Seismic Regulations The Building Seismic Safety Council was put up in 1997 as an affiliate of National Institute of Building Sciences. Its main purpose is to promote safety of the public by providing guidelines to construction, designing,…
Concrete Constituent and Mix Design
Natural heavyweight aggregates include materials such as goethite, limonite, barite, illmenite, magnetite, and hematite, with specific gravities (SGs) ranging from about 3.5 up to about 5.3, leading to concretes with unit weights up to about 4100 kg/m3 . For higher unit weight concretes, synthetic materials such as Ferro phosphorous (SG 5.8 to 6.8) or scrap iron and steel punching (SG 7.8) can be…
Seismic Analysis and Response of Bare and Masonry-Infilled Reinforced Concrete Frame Structures
Since the infill walls play some roles during earthquakes, their design need consideration to withhold lateral forces. From a research conducted out, most concrete structures succumb to seismic loads due to: Failures of beam-column joints as a result of poor reinforcement at the joints and/or poor workmanship in installation of reinforcement beams; Basic failure that results from flexural weakness…
design and construction of a prestressed concrete tank
The principle behind the prestressed concrete tank is that the compressive stresses induced by the high-strength steel tendons inside a concrete member prior to the loads being applied will balance tensile stresses inflicted in the member during the service. It`s recognized that prestressing eliminates several design limitations and conventional concrete places on load and span and allows the…
