The connectivity properties of a weight-bearing network are exploited toenhance it's capacity. We study a 2-d network of sites where the weight-bearingcapacity of a given site depends on the capacities of the sites connected to itin the layers above. The network consists of clusters viz. a set of sitesconnected with each other with the largest such collection of sites beingdenoted as the maximal cluster. New connections are made between sites insuccessive layers using two distinct strategies. The key element of ourstrategies consists of adding as many disjoint clusters as possible to thesites on the trunk $T$ of the maximal cluster. The new networks can bear muchhigher weights than the original networks and have much lower failure rates.The first strategy leads to a greater enhancement of stability whereas thesecond leads to a greater enhancement of capacity compared to the originalnetworks. The original network used here is a typical example of the branchinghierarchical class. However the application of strategies similar to ours canyield useful results in other types of networks as well.Comment: 17 pages, 3 EPS files, 5 PS files, Phys. Rev. E (to appear
