Static-cyclic shear load tests and tensile tests on retrofitted masonry walls were conducted at UAS Fribourg for an evaluation of the newly developed retrofitting system, the S&P ARMO-System. This retrofitting system consists of a composite of carbon mesh embedded in a specially adapted high quality spray mortar. It can be applied with established construction techniques using traditional const...

Structural retrofitting is carried out as an economical alternative to demolishing and rebuilding existing masonry structures. Retrofitting provided offer structural upgrade damage-control. This paper presents the application of oriented strand board type 3 (OSB/3) for unreinforced walls. Out-of-plane bending test in form four-point loading was performed on six The results show that OSB/3 can c...

1. Abstract The distributed Genetic Algorithm (GA) for PC cluster with multi-core-CPUs is proposed as a time reducing method for determining the schemes of retrofitting existing buildings with Buckling restrained Brace (BRB). Nondominated Sorting Genetic Algorithm-II (NSGA-II), one of the derivative evolutionary algorithm in heuristic method, was applied since the optimization problem have a mu...

Retrofitting our current building stock is a vital part of meeting emissions reductions targets, using energy in a more efficient way and creating sustainable lifestyles. However, one of the key barriers identified is a lack of tools to support making retrofitting decisions. In this paper, the creation of a transparent and flexible building energy performance simulation model SdSAP is reported ...

This paper considers the survivability requirement for production operating systems that underlie typical information systems. Since economic incentives give competitive advantages to imperfect and therefore insecure software, it seems inevitable to consider retrofitting some form of security to existing systems. This approach has long been anathema in the security community. We outline the pra...

Traditional building retrofitting planning is a decision making process prior to the building retrofitting investment. Although the long term energy and financial issues of the retrofitting project are considered in some cases, the energy efficiency potentials due to the maintenance and operation of the retrofitted facilities are not sufficiently explored in existing studies. In the broad field...

A multi-panel PMC infilled system, using polymer matrix composite (PMC) material, was introduced as new conceptual design for seismic retrofitting. A proposed multi panel PMC infilled system was composed of two basic structural components: inner PMC sandwich infills and outer FRP damping panels. The PMC material had high stiffness-to-weight and strength-to-weight ratios. Therefore, the addition...
