Based on the maintenance requirement of seaport wharf, the glass tubes filled with TY-6638 polyester adhesive or cyanogen gel adhesive were embedded in the self-repairing concrete to make the simply supported beams. Through the third-point bending experiment, the repairing capability and its influencing factors of two kinds of adhesive beams were analyzed from loading capacity and flexibility. The results show the loading capacity of cyanogen gel adhesive beams and polyester adhesive beams can be restored averagely to more than 90.0% after repair,so self-repairing concrete for maintenance of seaport wharf is technically feasible, it deserves to be studied farther.

The flexural behavior of concrete beams reinforced with CFRP-PCPs composite rebars was studied. Experimental results showed that the deflection of beams reinforced with highly prestressed prisms is at service loads coMParable to deflection of steel reinforced beam. Flexural cracks of CFRP-PCPs composite rebars reinforced beams are hairline before prism cracking, and widened after the prism cracking. When the concrete beam was reinforced with the prestressed concrete prisms, the crack width decreased as the prestress in the prism increased.

Abstract: To study the flexural behaviour of plain cement concrete with self-compaction concrete using three point loading. We are using two different types of concrete (Plain Cement Concrete and Self Compaction Concrete). For this we are using M20 grade concrete. We cast cubes and beams of sizes 150x150x150mm and 150x150x700mm respectively.Based on the test results it is concluded that the flexural strength of the self-compaction concrete beams is more than the plain cement concrete beams. And in the combination also the flexural strength is more when the plain cement concrete layer is at the bottom while the selfcompaction concrete layer is at top.

This experimental research was performed to evaluate the shear and flexural behavior for two cases of reinforced concrete beams: ultrahigh-performance concrete (UHPC) and normal-strength concrete jacketed with UHPC. The experiment was performed to examine the optimum para-aramid fiber to reinforce the ductile UHPC, with the test variables fiber diameter and length. Beam tests were then performed to evaluate the performance of the UHPC and jacketed beams. The UHPC beam tests with and without stirrups were conducted to evaluate flexural and shear behavior, respectively. The beam tests with and without jacketing were conducted to evaluate the reinforcement performance of UHPC.

The purpose of this paper is to experimentally and theoretically study the flexural behavior of concrete beams reinforced with fiber reinforced polymer (FRP) bars. In this research, two series of concrete beams reinforced with GFRP and CFRP were tested up to failure. Beam stiffness was the same for all beams until the appearance of first cracks. Deflection at failure was identical for beams reinforced with GFRP and CFRP bars, but force at failure of CFRP reinforced beams bars was greater. The theoretical analysis for calculating deflections was carried out. The theoretical results were compared to the test results for the simply supported beam deflections, and the theoretical predictions agree well with the test results.

Experiments were conducted on 5 simply-supported composite steel-concrete beams (SCB) with compact steel sections to investigate their deflection behaviors. The influences of degree of shear connection and stud arrangement are discussed. The load-deflection relationships and the interface slip distribution along the span of the beam are analyzed. Based on the experimental research and theoretical analyses, the formulae are derived for the rigidity of the composite steel-concrete beams with partial shear connection. The predicted of deflection values are in good agreement with the experimental results.

This article is a inquiry about how Barrès (1862-1923) handles the religious rite of pilgrimage. Barrès stages in his writings three successive forms of pilgrimage, revealing what is sacred to him at different times. The pilgrimage to a museum or to the birthplace of an artist is typical for the egotism and the humanism of the young Barrès, expressed in the Cult of the Self (1888-1891). After his conversion to nationalism, Barrès tries to unite the sons of France and to instill in them a solemn reverence for “the earth and the dead” ; for that purpose he encourages in French Amities (1903) pilgrimages to historical places of national importance (battlefields; birthplace of Joan of Arc), building what Nora later called the Realms of Memory. The third stage of Barrès’ intellectual evolution is exemplified by The Sacred Hill (1913). In this book the writer celebrates the places where “the Spirit blows”, and proves open to a large scale of spiritual forces, reaching back to paganism and forward to integrative syncretism, which aims at unifying “the entire realm of the sacred”.

The springboard for this essay is the author’s encounter with the feeling of horror and her attempts to understand what place horror has in philosophy. The inquiry relies upon Leonid Lipavsky’s “Investigation of Horror” and on various textual plunges into the fanged and clawed (and possibly noumenal) abyss of Nick Land’s work. Various experiences of horror are examined in order to build something of a typology, while also distilling the elements characteristic of the experience of horror in general. The essay’s overall hypothesis is that horror arises from a disruption of the usual ways of determining the boundaries between external things and the self, and this leads to a distinction between three subtypes of horror. In the first subtype, horror begins with the indeterminacy at the boundaries of things, a confrontation with something that defeats attempts to define it and thereby calls into question the definition of the self. In the second subtype, horror springs from the inability to determine one’s own boundaries, a process opposed by the crushing determinacy of the world. In the third subtype, horror unfolds by means of a substitution of one determinacy by another which is unexpected and ungrounded. In all three subtypes of horror, the disturbance of determinacy deprives the subject, the thinking entity, of its customary foundation for thought, and even of an explanation of how that foundation was lost; at times this can lead to impairment of the perception of time and space. Understood this way, horror comes within a hair’s breadth of madness - and may well cross over into it.
