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...

Microalloyed S355N steel plates are extensively used in bridge and high-rise building structures. One of the factors affecting the mechanical properties is the size and morphology of inclusions. In this research, microalloyed S355N steel plates with different sizes of inclusions were examined. One contained long manganese sulfide inclusions (LI material) and the other had short ones (SI materia...

Response modification factors (R-factor) are used in current seismic building codes to reduce earthquake forces associated with seismic design level to determine force levels. In recent years, many authors have shown great interest in the development of seismic structural systems and several theoretical and experimental studies have been conducted to investigate performance of dampers but littl...

This paper presents results of a demolition survey in a major North American city that captured building age, building type, structural material and reason for demolition for 227 buildings. The findings challenge many common assumptions about building longevity, and, in particular, the relationship between structural material and service life. Although it is often believed that “durable” struct...

The objective of this study was to develop prediction mathematical equations to compute reinforcement steel quantity in traditional residential buildings based on 158 sets of data collected in the West Bank in Palestine. The records related to the quantities were collected from consultancy firms that provide reinforced concrete design services. The data were collected for residential buildings ...

Analytical strengths of reinforced concrete beams and columns based on reinforcing steel stress-strain curves with and without a sharp yield plateau and the nonlinear stress-strain behavior of concrete are compared with strengths calculated in accordance with the ACI Building Code to determine the feasibility of using the 0.2% offset method to define the yield strength of reinforcing steel. Com...

One of the heaviest problems of reinforced concrete structures consists in the steel armature corrosion. The steel armature condition affects, above all, the properties of horizontal structures. It is to be noted that the corrosion process itself may not be observable from the outside in many cases. This is why studies of non-destructive methods allowing the researchers to detect the degree of ...

Recycled aggregate concrete (RAC) is an environmentally friendly building material. This paper investigates the mechanical behavior of recycled aggregate concrete filled steel tube (RACFST) columns exposed to fire. Two groups of 12 columns were designed and tested, under axial compression, before and after fire, to evaluate the degradation of bearing capacity due to fire exposure. Six specimens...
