exceeded losses of nonstructural components from structural ones in most demolished buildings in previous earthquakes and its limitation on functionality of critical facilities and building serviceability after earthquakes should be got the point of view for accounting loss of building as a merit for building performance. this paper attempts to demonstrate the significant role of distribution p...

Dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. These walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. In this research intermediate dual system of steel moment frame was chosen with int...

This paper summarize the principles main methods for structural dynamic identification and presents the experiences in using operational modal analysis techniques in Civil Engineering field. Shown black-box modelling of system for describes the input-output relation of the system and given its application to 11 storey reinforced concrete building. The monitoring, experimental details and data-p...

High-rise flexible-frame buildings are commonly considered to be resistant to shaking from the largest earthquakes. In addition, base isolation has become increasingly popular for critical buildings that should still function after an earthquake. How will these two types of buildings perform if a large earthquake occurs beneath a metropolitan area? To answer this question, we simulated the near...

Precast prestreesed concrete braces are a new method for seismic strength of Concrete Structures which has the following benefits: a) no wet concrete work in construction site b) No bolt or anchorage to the existing frame c) easy to apply d) short construction period e) low construction cost, to evaluate seismic performance of strengthened structure a model consist of existing frame and concret...

1.1. The History of Precast Building Precast building has always been a challenge in terms of the attempt to build buildings, above all, more quickly, whilst at the same time meeting all the conditions of good quality construction. This paper deals with the precast mode of construction using a timber frame, of the panel type, suitable for buildings with 3-4 storeys above ground. Therefore, in t...
