A SUMMARY OF RESULTS OF SIMULATED SEISMIC LOAD TESTS ON REINFORCED CONCRETE BEAM-COLUMN JOINTS,BEAMS AND COLUMNS WITH SUBSTANDARD REINFORCING DETAILS

The results of some simulated seismic load tests on reinforced concrete one-way interior and exterior beam-column joints with substandard reinforcing details typical of buildings constructed in New Zealand before the 1970s are described. The tests were conducted using both deformed and plain round longitudinal reinforcement. The interior beam-column joint cores lacked transverse reinforcement and the longitudinal bars passing through the joint core were poorly anchored. The exterior beam-column joint units contained very little transverse reinforcement in the members and in the joint core. In one exterior beam-column joint unit the beam bar hooks were not bent into the joint core. That is, the hooks at the ends of the top bars were bent up and the hooks at the ends of the bottom bars were bent down. This anchorage detail was common in many older buildings constructed before the 1970s. In the other exterior beam-column joint unit the hooks at the ends of the bars were bent into the joint core as in current practice. The improvement in performance of the joint with beam bars anchored according to current practice is demonstrated. In addition, tests were conducted on interior joints with lap splices in the beam longitudinal reinforcement bars near the column face. The tests were conducted using both deformed and plain round longitudinal reinforcement. Tests were also conducted on columns with plain round bar longitudinal reinforcement and inadequate transverse reinforcement.

The reinforcing details were close to identical to those in an existing seven storey reinforced concrete building that was designed and built in New Zealand in the late 1950s.

The test results give an indication of the performance of beam-column joints and members with the above now out-of-date reinforcing details.

The test results reported are a summary of results reported in a number of publications written since 1994.     

The idea of a Jewish nation in the German discourse about emancipation

This article compares the German conservative conceptualization of Judaism and Jewish emancipation with that of liberals, from the Vormärz (1830–1848) to the Neue Ära (1858–1861). It argues that both conservatives and liberals understood Judaism not merely as a religion but also as a nationality. Yet while liberals acknowledged the national dimension of Judaism as a secularized culture, and even supported Jewish emancipation, conservatives developed a different concept. Since the 1830s, conservatives accommodated nationalism while investing the Christian State ideal with national meaning. This national‐religious construction was imposed on Judaism, which was similarly interpreted now as a synthesis between religion and nationality. In accordance with this conceptualization, conservatives rejected Jewish emancipation on national ground while advocating for the establishment of a Jewish nation‐state. This thesis diverges from the existing literature, in which the reluctance of conservatism to embrace nationalism until the 1870s stands as the consensual view.
