装配式挡墙砌块剪切试验研究

提出了一种新型装配式挡墙榫卯结构砌块,并对砌块不同组合模式下的层间抗剪强度进行了试验研究。结果表明,单一砌块随着榫卯数量的增加,其抗剪强度逐渐降低;竖向压力与砌块抗剪强度正相关,增加竖向压力能提高砌块抗剪强度,但是效果并不理想;进一步提出了砌块抗剪强度计算公式,进行了榫卯数量影响因素修正,公式计算结果与实测值符合较好,为进一步研究砌块挡墙的抗剪承载力提供了理论支持。

苏北通榆河上混凝土系杆拱桥的预制装配施工

在苏北通榆河沿线新建的数十座公路桥中，有十余座采用了混凝土系杆拱结构。在施工时，对系杆、拱肋等构件先在工厂预制，然后在现场按一定程序安装拼接，并施加预应力，形成内部超静定、外部静定的系杆拱结构体系。     

From Product to Process: Building on Urban-Think Tank’s Approach to the Informal City

Adriana Navarro-Sertich interviews a pioneer of the informal in architecture, co-founder and co-director of Urban-Think Tank (U-TT) Alfredo Brillembourg . Brillembourg explains how U-TT's work seeks to connect informal settlements with the formal city, enabling inhabitants to access services and infrastructure. U-TT is now taking the lessons it has learnt in working in Latin American cities, such as Caracas and São Paulo, elsewhere in the world with the aim of ‘working globally and acting locally’.
